Section 4465-H-9.0 - Additional Requirements for Open-beam, Hand-held RGDs

9.1 In addition to the requirements in Part H, Sections 6.0 and 8.0, the following requirements in this Section apply to open-beam, hand-held RGDs.

9.2 Procedures. All registrants possessing open-beam, hand-held RGDs shall have available for review to the Agency operating policies and procedures that contain measures to insure that:

9.2.1 Radiation protection is provided equivalent to that afforded in Part D, Section 13.0 of these regulations (Dose Limits for Individual Members of the Public);

9.2.2 Radiation protection is provided equivalent to that afforded in Part H, subsection 8.8(Primary Beam Attenuation);

9.2.3 The operator will not hold the object or target during operation of the RGD and that the operator's hands will not approach the primary beam;

9.2.4 The operator will not aim the primary beam at him/herself or at any individual during operation of the RGD; and

9.2.5 Operator radiation exposure is as low as reasonably achievable (ALARA), for example, by use of ancillary equipment that will reduce exposure.

9.3 Training. In addition to the training requirements of Part H, subsection 6.6.10 and Part H, subsection 8.10.10 above, the registrant shall provide training for all users and operators on the subjects in Part H, subsection 9.2. Records shall be maintained of all user and operator training.

9.4 Radiation Emission Limit. For hand-held RGDs, the limits of Part H, subsection 6.4.2 (Radiation Source Housing Radiation Emission Limits) and Part H, subsection 6.5 (Generator Cabinet or High Voltage Source Radiation Emission Limits), excluding the primary beam, shall be met if the radiation emission at any accessible surface of the RGD does not exceed 0.025 millisieverts (mSv), or 2.5 milliRem (mRem) per hour at 5 cm.

9.5 Extremity Monitoring. For the purposes of the requirements in Part H, subsection 10.1.10 (extremity monitoring), operators of hand-held RGDs shall be considered as working near the primary beam. Extremity dosimeters are required if dose may exceed 10% of the annual occupational dose limit.
