Section 6 CCR 1007-1-8.11 - RGDs Used in Human Body Security Screening or Vehicle Screening for Public Protection

The requirements in this section are in addition to the General Requirements in 8.4, 8.5, and 8.6.

A person must request Department approval for a RGD to be used for Human Body Security Screening or Vehicle Screening involving intended exposure of human occupants to the primary beam for public protection purposes. Such persons shall submit the appropriate form or submit in writing the following information to the Department for evaluation and approval, and demonstrate how the dose limits in 8.11 will be met:

8.11.1 Efficacy Evaluation.

An evaluation of all known alternate methods that could achieve the goals of the security screening program, and why these methods will not be used in preference to the proposed approach utilizing ionizing radiation.

8.11.2 Equipment Evaluation.

RGDs used for human body security screening shall be evaluated every 12 months by a Qualified Inspector for radiation dose and optimization of image quality. Evaluation of optimization of image quality shall be done in accord with the system manufacturer's specifications, recommendations, and quality assurance procedures or, in the absence of manufacturer provided information on image quality, the recommendations of a nationally recognized organization or Qualified Inspector.

8.11.3 Dose Limits for General-Use Systems.

For general-use screening systems, where the system is used without regard to the number of individuals scanned or number of scans per individual in a year, an effective dose for a single complete screening shall be limited to 25 µrem (0.25 µSv).

8.11.4 Dose Limits for Limited-Use Systems.

For limited-use screening systems, where the system is capable of operation greater than 25 µrem (0.25 µSv) per screening, and is used with discretion, the effective dose per screening shall be less than or equal to 1 mrem (0.01 mSv).

8.11.5 Dose Limits for Repeat Security Screenings.

Individuals subject to repeat security screening at a single venue shall not receive an effective dose greater than 25 mrem (0.25 mSv) in any one year at the registrant's facility.

8.11.6 Requirements for vehicle or container screening systems.
A. When the procedures for operation of a RGD used for security screening of vehicles includes knowingly exposing human occupants to the primary beam when screening vehicles, structures or containers, the system shall be subject to the same requirements as general-use or limited-use systems as provided in 8.11.1 through 8.11.5.
B. If the requirements in 8.11.3 through 8.11.5. cannot be met if vehicle occupants are knowingly exposed to the primary beam of a security screening system, then there shall be means to assure the occupied portion of the vehicle is outside of the scan area while the primary beam is emitted or procedures shall be established and implemented to assure that no occupants are present in the vehicle during screening.
C. The effective dose to an individual for a single inadvertent exposure to the primary beam shall not exceed 500 mrem (5 mSv) and should not exceed 100 mrem (1 mSv). The reliability of the procedure used to assure that there are no occupants of a vehicle to be scanned shall be commensurate with the potential severity of an inadvertent exposure. If the 500 mrem (5 mSv) limit cannot be assured, a pre-screening with a mode or system which can meet the limits in 8.11.3 through 8.11.6 shall be used to verify there are no occupants in the vehicle being examined.
