Study Notes

Radiation Surveys, Agencies and Regulations

The primary objective of radiation surveys and regulations is to ensure that individuals receive doses below the permissible levels
Licensing and inspection regulations are the responsibility of the Federal Authority for Nuclear Regulation (FANR)
The regulations control the use, transfer, and disposal of licensed material, ensuring that the total dose received by an individual does not surpass the established safety standards
The UAE Nuclear Law (2009) based on the 2008 policy, outlines the key principles of nuclear non-proliferation, safety and security, transparency, partnership with other nations and expert organizations, and long-term sustainability
The Nuclear Regulatory Commission (NRC) regulates the safety of occupational workers and the public regarding all reactor-produced by-product materials, including their use and disposal
Agreement States, authorized by the NRC, regulate naturally occurring radioactive materials and reactor-produced by-product materials within their borders
General licenses are for in-vitro use only, with a maximum activity limit of 200 uCi
Specific licenses of limited scope are issued to physicians in private practice for specified use in humans, with the authorized user's name indicated on the license
Specific licenses of broad scope are issued to medical institutions for medical use, supervised by the Radiation Safety Committee
The Food & Drug Administration (FDA) regulates all drugs used in humans for therapeutic and diagnostic purposes, including Investigational and New Drug Applications
The Department of Transportation (DOT) sets guidelines for packaging, transportation, and radioactivity limits for radioactive materials
The Radiation Safety Committee (RSC) assists in the development and implementation of radiation safety programs to ensure the safety of patients and workers
The Radiation Safety Officer (RSO), typically a medical physicist or radiologist, develops and implements radiation safety programs for the facility
The National Council on Radiation Protection (NCRP) recommends dose limits, and the ALARA program aims to maintain exposures as low as reasonably achievable below these limits
Radiation surveys are conducted to monitor areas where radiopharmaceuticals are prepared and stored
Surveys should be conducted at the end of each day for areas where pharmaceuticals are prepared, weekly for areas where radiopharmaceuticals or radioactive wastes are stored, and weekly using wipe testing for areas where radiopharmaceuticals are prepared or stored
Survey instruments should be calibrated before first use, annually, and after any repairs
Calibration records should be kept for at least 3 years
Survey instruments should be checked daily using a dedicated check source and battery check
Dose calibrators require constancy, accuracy, linearity, and geometry testing periodically
Dose calibrator records should be kept for at least 3 years and include the model, serial number, date, identity of the check source, measured activity, and initials of the person who performed the test
Radiation areas are classified as unrestricted, restricted, and controlled areas
Unrestricted areas have radiation levels not exceeding 2 mR/hr and do not require access control
Restricted areas have radiation levels exceeding those of unrestricted areas and require access control
Controlled areas are outside of restricted areas, and access may be limited
Caution signs with the standard radiation symbol using magenta or purple on yellow background are used to indicate radiation areas
Caution: High Radiation signs are used for areas with radiation levels greater than 5 mR/hr at 30 cm from the source
Caution: High Radiation Area signs are used for areas with radiation levels greater than 100 mR/hr at 30 cm from the source
Caution: Very High Radiation Area signs are used for areas with radiation levels greater than 500 rads/hr at 1 meter from the source
