Notify the RSO of any violations or deviations from the rules, regulations, procedures, ALARA practices, or unusual events involving the use of radioactive material or exposure. Gamma spectroscopy is a method used to identify the radioisotopes present in a radiological sample and quantify the amount of radioactivity in that sample. The symbol is magenta, purple, or black on a yellow background. Therefore, every individual is responsible not only to maintain compliance with all rules, regulations, procedures, and policies that govern the use of radioactive material, but also to promote a safe working environment through his/her radiation and contamination control practices. 7.4. Most radioactive materials used for research at Stanford University and VA Palo Alto are low energy beta emitters, low energy photon emitters, or radionuclides that are used in nuclear medicine. b. If the effective dose is greater than 5000 mrem or the organ equivalent dose is greater than the value derived by dividing 5 rad by the associated weighting factor (see table below), before the next CRSCo meeting by the Chairman or his designee, the Radiation Safety Officer (RSO) or his designee, and one physician faculty member, or be approved at the next CRSCo meeting. For someone residing in the US, the annual background exposure is approximately 6.3 mSv (633 mrem), but some locations can be much higher. Direct reading portable airborne radiation monitors can be used to provide a nearly instantaneous measurement of airborne radon concentration. Radiation safety training, your supervisor, or a health physicist are all good resources to determine the proper shielding for the type of radiation you are exposed to. Practice and promote ALARA principles and standards. Radiation exists all around us, from both natural and manmade sources, and is in two forms: ionizing and non-ionizing radiation. Ancillary Worker examples include: Personnel who would not normally be expected to encounter radioactive material or radiation sources in the course of their employment. Because health physics supports the uses of ionizing radiation it is helpful to discuss the reasons why this type of radiation is important. Nausea, vomiting, diarrhea, and skin erythema within four hours may indicate very high (but treatable) external radiation exposures. 90Y has a half-life of about 64 hours. These devices can often be set to trigger an alarm at a user specified level of measured airborne radioactivity. Studies show that cargo handlers get very little radiation exposure from handling them. Each individual having a previous or on-going radiation exposure history with another institution is required to submit anAuthorization to Obtain Radiation Exposure Historyform. In compliance with federal and state requirements, the University holds licenses that require the University to have policies and procedures to regulate safe use and storage of radioactive materials and devices. They may also institute on-site inspections. There are some exceptions to posting if approved in advance by Health Physics and if the material is supervised by a trained individual approved to handle radioactive material by Health Physics. What are the Units of Radiation Activity? Radiation Safety Programs include Radioactive Materials, Analytical X-ray Equipment, and Laser Safety. When transporting the patient, do not share elevators with other staff or patients. SHC, SCH and VAPAHCS are responsible for lead apron inspection and inventory. (2014). Related News and Articles. Medical isotopes are chosen and used in humans because of the quick decay properties of the isotope. Policies and procedures developed will delineate responsibilities to ensure that ionizing Nursing personnel are not required to wear radiation monitoring badges. If the gloves are in the primary beam the glove will cause a substantial x-ray tube output boost to correct for the attenuation of the beam, which an increase in dose to both the patient and the operator. 5.2.4.1. Scaler / counters are sometimes equipped with scintillation detectors, G-M detectors, proportional detectors, or passivated implanted planar silicon (PIPS) detectors. For a missing dosimeter aLost/Damaged Dosimeter ReportFormis required. If a dosimeter is lost frequently, and if it is not required due to the exposure environment, it will be cancelled. X-rays are a type of energy similar to light but like gamma rays pass easily through fairly thick materials. When badges are required, it is both the individual and the supervisors responsibility to ensure that they are worn. For shielding of rooms containing medical X-ray equipment or rooms with other medical X-ray imaging devices, the National Council on Radiation Protection and Measurements (NCRP) recommends that the shielding design goal be 500 mrad (5 mGy) in a year to any person in controlled (restricted) areas. Dosimetry requestscan be made on this website. 4.1.3.3. All badges and rings are collected by the designated department or location contact to be processed by a contractor. If the package is not contaminated remove or switch the radiation label to the empty notice. 3.2 NUREG: The abbreviation for the US Nuclear Regulatory Commissions regulations. Note: On September 30, 2014 the State of California issued an exemption to Title 17 (17CCR), Section 30450(a)(1), 30450(a)(2) which required a fluoroscopy permit to be issued for someone who positions a patient, or positions fluoroscopy equipment. Responsibility for these duties may not be transferred to other individuals. This is true for most operations in general industry, construction, shipyards, marine terminals, and longshoring. Today, in the US, medical procedures from ionizing radiation account for 51% of our average annual dose from radiation (the other 49% is from naturally occurring sources such as cosmic rays, radon, and soils). Engineering controls, in some cases, may be incorporated into facility design. Any electronic device that has fast-moving electrons is a potential source of ionizing radiation. 80 kVp). The RSO shall determine and document the sanctions, if any, necessary to prevent recurrence. The 90Y is delivered by loading the yttrium into tiny resin microspheres. If a badge is returned late, higher work exposures cannot be investigated in a timely manner. When half of the original atoms have decayed, the material is said to have gone through a half-life. During the next half-life, half of the remaining atoms will continue to decay; leaving one-fourth of the original and so on. External exposureisradiationthat comes from somewhere outside the body and interacts with us. NRC Material License No. Because nuclear medicine patients might undergo additional examinations, other hospital staff might also be exposed. YSM Home. Do not release the room to housekeeping until caution signs have been removed by the hazardous waste technician. The Electromagnetic Spectrum: Non-Ionizing Radiation. Thyroid shields with defects greater than 11 square mm. Receipt and return of all radioactive packages is documented by entering the required data in to the Pinestar Database or other Nuclear Medicine Database. Only necessary personnel should be in the room when the unit is operating. Contact Health Physics at (650) 723-3201. The source ofradiationcan be a piece of equipment that produces theradiation, like an x-ray machine, or it can be from radioactive materials in a container. OSHA Method ID-208 is a diffusing sampling method that describes the use of a short-term (2-7 day) electret-passive environmental radon monitor (E-PERM). 5.2.3. Notify the RSO if you know or suspect you are pregnant, or follow other facility channels as defined in policies and . Your radiation exposure will be about _____ mSv. No significant changes were made from May 1, 2018, except to move to the template. Participate in the Quality Control Program. Copyright Complaints, Types of Radiation Emissions and their Decay. Use of these devices is now very limited having largely been replaced with the use of EPDs. The limits vary depending on the affected part of the body. Promote proper infection control during radiographic procedures. You will be exposed to radiation during this research. A type of PRD, a Spectroscopic Personal Radiation Detectors (SPRD), can also measure the gamma spectrum of the radiation source, which can be used to identify the radioisotopes present. A lead apron does not provide adequate shielding for 18F or 131I therapy patients (most diagnostic imaging tracers can not be shielded with a lead or lead equivalent apron). Nuclides which are used for diagnostic purposes, scans, or images have short half-lives. OSHAs Ionizing Radiation standard requires employers to conduct dose monitoring when a worker who enters a restricted area receives or is likely to receive a dose in any calendar quarter in excess of 25% of the applicable occupational limit (or 5% for workers under age 18) and for each worker who enters a high radiation area (1910.1096(d)(2) and 1910.1096(d)(3), 29 CFR 1926.53). Sample echocardiography policy for radiation safety. These devices can provide a continuous readout of the wearers radiation dose, dose rate, and can be set to alarm at user defined dose thresholds and dose rates. Faculty members of an approved medical school who are granted a certificate of registration by the Medical Board of California (code BPC 2113) are exempt from the requirement to obtain a Fluoroscopy Supervisor and Operator permit. Radiation survey instruments can be used to evaluate exposure rates, dose rates, and the quantities (activity) of radioactive materials and contamination. For example, a leaded apron will reduce X-ray doses to covered areas. Direct deliveries may arrive on any day and at any time of the day. There is some flexibility in the regulations on how an emergency would be defined. If lead aprons are used, wear the whole body badge outside of the apron at the collar and clip the fetal badge under the apron. It further provides a list of sub-programs and procedures which shall be maintained to ensure the policy meets its intent. Radiation Safety Policies. Health Physics will assure that appropriate technical assistance and guidance is provided for achieving compliance with the above. Prior to returning the empty package (usually an ammo box), swipe and monitor the package for contamination. 124/105). Personal Radiation Detectors (PRD) are small electronic devices designed to alert the wearer to the presence of radiation. If, for any reason, the license is suspended or terminated no one will be able to use radioactive materials of any kind. . The exemption permits Staff operating under the direct oversight of a licentiate in possession of either current and valid Fluoroscopy Supervisor and Operator permit or a current and valid Radiology Supervisor and Operator certificate (permitted licentiate) issued by the Department, are hereby granted an exemption to requirements listed in 17 CCR 30450 (a)(1) and (a)(2), provided that all of the following conditions are met: Some electrical equipment operating at potentials of 20 kVp and above is capable of producing x-rays. Steven M. CarrInterim Vice President of Research, Western Michigan UniversityKalamazoo MI 49008-5200 USA(269) 387-1000Contact WMU, WMU Notice of Non-DiscriminationLand Acknowledgement Statement. Exposure to a research subject less than 18 years of age. It meets quarterly. 4.1.4.5. Provisions need to be made to potentially deal with thousands of such persons. 186-187) published results from a study on radiation exposure to sonographers from patients who were injected with the PET (positron emission tomography) imaging radiopharmaceutical18F-fluorodeoxyglucose (FDG). Drugs also leave the body physiologically, usually through urine. Report any CT scan of a wrong body part or repeated CT scan to Health Physics for dose estimation, except if the repeat scan is necessary due to patient motion effects. Background radiation consists of the radiation exposures received from both natural and man-made sources. Conversions are as follows: With radiation counting instruments (e.g., Geiger counters, liquid scintillation counters), radiation can be measured in units of disintegrations per minute (dpm) or, counts per minute (cpm). Some radiation sources, such as most X-ray equipment and some accelerators, must be registered with a state agency (e.g., state radiation control agency, state health department) or local agency (e.g., health department) and different registration requirements may apply, depending on the agency. The Agency supports other federal, state and local agencies by developing federal guidance and technical reports on radiation protection, and assists in response to radiological emergencies. For example, these non-radiological safety and health hazards may include electrical hazards from associated electrical equipment and extension cords, shift work and long work hours, worker ingress (entry) into and egress (exit) from shielded enclosures (e.g., at fixed industrial radiography facilities), and laser hazards if lasers are incorporated into radiation-emitting equipment (e.g., lasers are sometimes used to align an external beam with the target). Examples of Required Licentiate Certificates: A Fluoroscopy Supervisor and Operator permit allows the individual to do any of the following: Note: Only persons authorized by the individual in charge of the installation shall operate fluoroscopic equipment. Patients will receive the following instructions: Note:Adult visitors should typically remain 3 feet or more away from the patient. The Committee meets at least once during each calendar quarter, or more frequently, at the discretion of the Chair. This allows for the determination of what the radioactive material is (radioisotope identification) and how much radioactive material is present (radioactivity). A single high-level radiation exposure (i.e., greater than 100 mSv) delivered to the whole body over a very short period of time may have potential health risks. Adding the amount of fixed and removable contamination provides the amount of total contamination. RADIATION SAFETY STAFF Under the direction of the RSO . 131I MIBG is used to treat neuroendocrine tumors. 4.1.2.3 Take actions necessary to ensure all radiation safety practices comply with the rules and regulations governing the use of radioactive material or radiation producing machines. 4.4. Dosimeters are typically assigned to an individual to record only their radiation dose. Atmospheric testing is now banned by most nations. There are some exceptions to labeling for quantities less than 10 CFR 20 Appendix C limits, if approved by Health Physics and if the material is supervised by a trained individual approved to handle radioactive material by Health Physics. Bethesda, MD: NCRP. The ultimate goal of the Army Radiation Safety program is to keep radiation exposure As Low As Reasonably Achievable (ALARA) to Soldiers, Civilians, Contractors, the general public, and the environment. People who are externally contaminated can become internally contaminated if radioactive material gets into their bodies. Personnel who are required to wear lead aprons or other similar radiation protection devices should visually inspect these devices prior to each use for obvious signs of damage such as tears or sagging of lead. If you are informed that radiation accident victims will be sent to the hospital, immediately notify the nuclear medicine department, Health Physics, the Radiation Safety Officer and others who have radiation exposure expertise. Purpose. A non-occupational worker, such as a mother or father, can hold the patient. The Transportation Index (TI) noted on the packages with Yellow II or Yellow III labels is the dose rate, in mrem/hour, at 1 meter from the package surface. Sampling and analytical methods and equipment allow radiation safety professionals to identify areas with radioactivity, including where radioactive materials have contaminated environmental surfaces and other objects as well as environments that have radioactive materials in the air. This section discusses several sampling methods. Make prompt decisions without having to consult with higher management, particularly in case of an emergency concerning radiation. Diffusive samplers can be deployed for several days to months to measure the average airborne radon concentration over the sampling period. Radiation Oncology Medical Physics and Health Physics will jointly prepare information for submittal and review by RHB (submit to RHB >60 days prior to installation or upgrade) including: Shielding calculations or supported reasoning for why shielding is not required, Safety feature description such as interlocks, audible/visual beam-on indicators, RHB returns their comments and concerns or approves shielding, RHB approves energization of the beam for the purposes of obtaining applicable TG report/calibration and the environmental survey, Submit Physicists Report of Safety Inspection and Comprehensive Environmental Survey, RHB gives final approval (approval may take up to 60 days) to begin patient therapy. People are constantly exposed to small amounts ofionizing radiationfrom the environment as they carry out their normal daily activities; this is known as background radiation. Do not use the automatic brightness control, as this will drive the tube current and high voltage up, resulting in unnecessary radiation exposure to personnel and wear on the tube. 2. Because removal of interlock keys will stop X-ray or particle beam production, such interlock systems rely on constant monitoring of all interlock keys and appropriate worker training for controlled access to high radiation areas. The RSM describes UC Berkeley policy and practice regarding the use of ionizing radiation and serves as a source of the radiation license requirements. The radiation dose from consumer products is relatively small as compared to other naturally occurring sources of radiation and averages 0.1 mSv (10 mrem) per year. Bioassay samples most commonly include urine, feces, and blood. Most patients need to wait about an hour for the drug to be taken up in the body, and the PET/CT setup and scan can also be about an hour, which means, by the time a 18F patient leaves nuclear medicine the isotope has already been reduced by half due to physical half-life decay alone. In order to read PDF files you need to have the Adobe Acrobat Reader. Some types of radioactive materials stay in the body and are deposited in different body organs. The following scenarios are adapted fromMedical Management of RadiologicalCasualties Handbook(Jarrett, 1999). Warning systems should be checked regularly for proper function. Do not spend any more time in patients room than is necessary to care for patient. Lab Moves: If you are moving to a new lab space or inactivating, please see our licensing page. If the gonads are not in the primary field, the radiation exposure drops off rapidly. External contamination occurs when radioactive material, in the form of dust, powder, or liquid, comes into contact with a persons skin, hair, or personal clothing. EPA-402-R-10003, Federal Guidance Report #14, Occupational Safety and Health Administration, Outreach Training Program (10- and 30-hour Cards), OSHA Training Institute Education Centers, Radiation Emergency Preparedness and Response page, Report No. Radioactive Materials, Radiation Areas, High Radiation Areas, Very High Radiation Areas, Airborne Radioactivity Areas, shipping containers and vehicles shall be marked or posted as required by various regulations. This policy establishes the duties and responsibilities for the Radiation Safety Program to ensure compliance with the United States Code of Federal Regulations (CFR) and Public Acts of the State of Michigan. 5.1.2.2. This policy is designed to provide Authorized Users, Radiation Workers and other staff of University of Health Sciences and Pharmacy in St. Louis and the affiliated personnel of the Center for Clinical Pharmacology a convenient reference to the compliance requirements of the Radiation Safety Program related to the use of radioactive materials. With minor therapies, such as radioiodine for treatment of hyperthyroidism, the amount of radioactivity administered is sufficiently small to permit outpatient treatment of these patients. An x-ray device was first used in 1896 and permitted non-invasive imaging of internal human structures. Formal Declaration of Pregnancy is voluntary. Any worker likely to receive radiation exposures in excess of 10% (500 mrem) of the applicable limit and individuals who enter in a radiation area greater than 5 mrem per hour (e.g., persons who work within 6 feet of a fluoroscopy tube). Leaded eyewear and thyroid shields are recommended if the operator performs patient-side work during the procedure. These radiochemicals and devices are used in research and clinical settings, such as when conducting research in a laboratory or . After injection into the artery supplying blood to the tumors, the spheres are trapped in the tumors vascular bed, where they destroy the tumor cells by delivering the beta radiation. Sealed radioactive sources are often made by encapsulating the salt or metal of a radionuclide into a welded metal container whose size typically ranges from smaller than a grain of rice to the size of a golf ball. 21-03336-09 issued to Western Michigan University on July 07, 2017. Visitors should remain at least 6 feet from the patients and should not stay more than 2 hours per day (unless other information is provided). Fresh air may be mixed with the exhaust stream so as to reduce the concentration of radioactive inert gas. 4.1.4.1 Responsible for complying with all rules, regulations, procedures, and policies that govern the use of radioactive material and radiation producing machines. A resident or fellow working under the supervision of a Certified Fluoroscopy Supervisor physician does not need to be certified. Personal air sampling collects air from the breathing zone of a worker, while an area sample collects general room air. 4.1.5.3. Personnel shall not perform this service except infrequently and then only in cases where no other method is available. Contact Health Physics at (650) 723-3201. 4.1. If these items are not disposable, they shall be thoroughly washed with soap and running water. 144: Radiation Protection for Particle Accelerator Facilities, Report No. Federal guidance reports are used by federal and state agencies in developing. People are exposed to radiation from cosmic rays, as well as to radioactive materials found in the soil, water, food, air and also inside the body. Regulatory NRC/CDPH Limit. Therefore, exposure to a non-radiation worker must not exceed 100 mrem/year. In addition to worker safety, patient safety is a concern for interlock systems for medical X-ray equipment or accelerators. Emergency Plan consists of procedures used to minimize the potential exposure of or to the general public and radiation workers by providing immediate responsive actions to emergencies involving an unplanned release of radioactive material or unplanned exposure rates. Radiological contamination sampling is used to evaluate the presence of unwanted radioactive materials, also known as contamination, deposited in an uncontrolled manner on or in objects and on surfaces. This policy applies to all personnel in facilities or on property owned or controlled by WMU and utilizing radioactive materials or radiation producing devices. ALARA . For females, the gonads are not visible or generally localized in the abdomen. Research protocols involving human subjects must also be approved by Stanfords Institutional Review Board (IRB). For minors, approval levels are 10% of those listed above and in the table. Evacuation may be necessary. All individuals who work with radioactive materials or radiation devices are responsible for knowing and adhering to applicable requirements. The nuclide used in liver cancer therapy for radioembolization is 90Y and has a half-life of 64 hours. Radioactive Material Authorizations 4.4. 4.1.3.4. 2Radioactive Drug Research Committee proposals require full CRSCo approval. Examples of commonly used PPE for radiation protection from X-rays and gamma rays include: Although respirators are typically the last choice for controlling internal exposure to airborne radionuclides, reducing internal radiation dose, employers should ensure that workers use properly selected respirators and wear those respirators when required. In the USA, the average effective whole body dose from radon is about 200 mrem per year. The Radiation Safety Policy further stipulates the duties and responsibilities for the development, implementation, and oversight to ensure the safe use of radiation. A typical 0.5-mm lead-equivalent apron or thyroid shield will provide 85% to 95% attenuation of scattered fluoroscopy x-rays. A person qualified by both training and experience to formulate radioactive drugs, A person with special competence in radiation safety and radiation dosimetry, The remaining members of the committee shall be selected from the pertinent disciplines that may be required to carry out the provisions of the law. Fluoroscopic lead aprons are to be discarded if inspections determine: All machines, more specificallyx-ray tubes, that generate ionizing radiation, including those for either diagnostic or therapeutic purposes, must be registered with the State of California (unless they are located in a Federal facility) within 30 days of acquisition (CCR, Title 17, section 30108). Providing workers with information and training is closely tied to awareness of regulations because federal and state regulations often include performance and safety standards for specific radiation-producing equipment or radiation sources. These devices are often portable and are used to measure the amount of alpha or beta radiations on a radiological sample. 147: Structural Shielding Design for Medical X-ray Imaging Facilities, Report No. A fetal monitoring badge, if appropriate. The radioactive drugs are given to patients for the detection and treatment of disease. A typical radiation dose from a whole body CT is about 15 mSv (1500 mrem). 2 mrem. Bioassay sampling is sometime used in occupational settings to determine the uptake of radioactive material for radiological workers. Employees who become pregnant and must work with radioactive material or radiation sources during their pregnancy, may choose to contact Health Physics and complete a confidential Declaration of Pregnancy form. Primary systems involved will be skin, intestinal tract, and bone marrow. 7.1. Identify how many people need to be badged compared to the number that want to be badged. Before using any new or remodeled rooms or facilities or any new or relocated X-ray equipment, a qualified expert should conduct an area survey and evaluate shielding to verify radiation protection behind shielding materials.
