06.F.03 Radiation Safety Program.
- Operations involving radiation hazards, and users of radioactive material or radiation generating devices, shall develop and implement a Radiation Safety Program.
- (1)The program must be managed by the RSO and based on sound radiation safety principles that must keep occupational doses and doses to the public ALARA.
- (2) The RSO is responsible for performing or ensuring the performance of an annual review of the program. Documentation of the review must be retained for two (2) years.
- (3) A Radiation Safety Committee (RSC) must be established in accordance with 10 CFR 20 and DA PAM 385-24 as part of the Radiation Safety Program.
The RSC is an important part of the Radiation Safety Program.
- All personnel entering an area where radioactive material or radiation generating devices are used, and where there is a potential for an individual to receive a Total Effective Dose Equivalent (TEDE) of 100 mrem or more in one (1) year, must receive instruction in:
- (1) The presence of the material or device;
- (2) Health and safety problems associated with exposure to radiation, including the potential effects of radiation on a pregnant female, the fetus, or embryo;
- (3) Precautions and controls used to control exposure;
- (4) Proper use of instrumentation and dosimetry in the area;
- (5) The Radiation Safety Program required in 06.F.03.a; and
- (6) Their rights and responsibilities.
- Users of radioactive material or radiation generating devices without a potential to receive a TEDE of 100 mrem or more in one (1) year and visitors to a site must coordinate with the RSO for appropriate training.
- The Radiation Safety Program will include plans and procedures for handling credible emergencies involving radiation and radioactive materials. This will include coordination with civilian and/or military emergency response organizations as necessary.
06.F.04 Dose Limits.
| Body Part | Annual limits with RSSO approval |
Annual limits without RSSO approval |
Suggested ALARA limit |
|---|---|---|---|
| Whole body | 5 rem (0.05 Sv) | 0.5 rem (0.005 Sv) | 0.1 rem (0.001 Sv) |
| Individual organ | 50 rem (0.0 Sv) | 5 rem (0.05 Sv) | 0.5 rem (0.005 Sv) |
| Lens of eye | 15 rem (.15 Sv) | 1.5 rem (0.015 Sv) | 0.15 rem (0.0015 Sv) |
| Skin or extremity | 50 rem (0.0 Sv) | 5 rem (0.05 Sv) | 0.5 rem (0.005 Sv) |
- Occupational dose limits shall be based on the TEDE. > See Table 6-1.
- (1) An annual (calendar year) limit that is the more limiting of: 5 rem [0.05 sieverts (Sv)] TEDE, or the sum of the deep dose equivalent and the committed dose equivalent to any individual organ or tissue of 50 rem (0.5 Sv), or 15 rem (0.15 Sv) to the lens of the eye, or 50 rem (0.05 Sv) shallow dose equivalent to the skin or any extremity.
- (2) Without the written approval of the USACE Radiation Safety Staff Officer (RSSO), the annual occupational dose shall not exceed the more limiting of: 0.5 rem (0.005 Sv) TEDE, or the sum of the deep dose equivalent and the committed dose equivalent to any individual organ or tissue of 5 rem (0.05 Sv), or 1.5 rem (0.015 Sv) to the lens of the eye, or 5 rem (0.05 Sv) shallow dose equivalent to the skin, or any extremity.
- (3) To keep doses ALARA, the user must set administrative action levels below the annual dose limits. These action levels must be realistic and attainable. Suggested action levels are the more limiting of: 0.1 rem (0.001 Sv) TEDE, or the sum of the deep dose equivalent and the committed dose equivalent to any individual organ or tissue of 0.5 rem (0.005 Sv), or 0.15 rem (0.0015 Sv) to the lens of the eye, or 0.5 rem (0.005 Sv) shallow dose equivalent to the skin or any extremity.
- (4) Any exposure in excess of an ALARA limit requires investigation by the RSO.
- In accordance with DA PAM 385-24, planned special exposures must not be performed.
- No employee under 18 years of age must receive occupational exposure to ionizing radiation (excluding exposure to Radon-222).
- The dose to a declared pregnant employee must not exceed 0.5 rem (0.005 Sv) during the entire gestation period and efforts must be made to avoid variations in a uniform monthly exposure rate. If the dose to the embryo/fetus is between 0.05 rem and 0.5 rem at the time of declaration, then dose to the embryo/fetus is limited to 0.05 rem for the remainder of gestation.
