- NOTICE -
IF YOU ARE A RAD-WORKER NEEDING TO UPDATE YOUR REVIEW OF THE GENERAL ACCESS RWP FOR 2009 PLEASE DO NOT SIGN THE ELECTRONIC RWP YET.  THE CURRENT RWP IS THE 2008 VERSION AND WILL BEUPDATED SOON.  PLEASE AWAIT INFORMATION CONCERNING WHEN TO SIGN UP ON THE 2009 PERMIT.

Radiation Control Department supports the laboratory by helping to protect laboratory workers, the environment and the general public from unnecessary ionizing radiation exposure due to lab operations. Jefferson Lab is committed to having a high quality radiation control program which is conducted using sound industry practices. Applicable regulations, such as 10 CFR 835, will be the standard of care for the program, and ALARA (As Low As Resonably Achievable) will be the guiding principle. The radiation program relies on training, workplace monitoring, work controls, material controls, and environmental monitoring. Radiation Control professionals and technical staff are assisted by other specially trained lab staff to implement and monitor the program.

Jefferson Lab makes the following policy statements in support of its radiological controls program and applicable legal requirements.

  1. SURA/Jefferson Lab management is responsible for compliance with the requirements of 10 CFR 835 and implementation of related programs, plans and schedules.
  2. No employee or contractor of SURA/Jefferson Lab, or any DOE employee shall take or cause to be taken any action inconsistent with the requirements of 10 CFR 835 or any related program, plan, schedule, or other process established or required by 10 CFR 835.
  3. Nothing in this RadCon Manual or any part of 10 CFR 835 shall be construed as limiting actions that may be necessary to protect health and safety.
  4. Radiation dose will not exceed the following statutory limits:
    1. Radiation workers shall not receive a dose of more than 5 rem per calendar year total effective dose equivalent.
    2. Non-radiation workers shall not receive a dose of more than 0.1 rem per calendar year total effective dose equivalent.
  5. Exposure to ionizing radiation should be kept ALARA, taking into account the net benefit obtained as a result of the exposure. There should not be any occupational radiation exposure of workers to ionizing radiation without the expectation of an overall benefit from the activity causing the exposure. This policy is applied to personnel and environmental radiation protection.
  6. Jefferson Lab has established action levels and design goals consistent with ALARA. Action levels are below the statutory limits given above. If the action level is exceeded, a local investigation shall be made to ensure that ALARA is being observed. Design goals were utilized in the design of Jefferson Lab and are used in any subsequent modification or new construction. They are lower than action levels and are intended to provide assurance that ALARA is included in the basic design and operation. Design goals include considerations for:
    1. maintaining individual worker dose less than 250 mrem per year
    2. preventing degradation of groundwater quality
    3. controlling of contamination by engineered means where possible
    4. minimizing the generation of radioactive material.
  7. The Jefferson Lab Radiation Review Panel (JRRP) serves as an ALARA Committee. The membership includes managers and workers from the scientific and technical Divisions and Departments and the Radiation Control Department. The Jefferson Lab Radiation Review Panel Charter is found in the Jefferson Lab Environmental Health and Safety (EH&S) Manual ( Chapter * 2240* Jefferson Lab EH&S Committees). The JRRP makes recommendations to management to improve processes in minimizing radiation exposure and preventing radiological releases. This committee may evaluate items such as construction, design, and modification of laboratory facilities and systems and planned major modifications or work activities.
