					 dosimetry system available for use. To satisfy this requirement, one of the
					 following two conditions shall be met.
1. The
					 system shall have been calibrated using a system or source traceable to the
					 National Institute of Standards and Technology (NIST) and published protocols
					 accepted by nationally recognized bodies or by a calibration laboratory
					 accredited by the American Association of Physicists in Medicine (AAPM). The
					 calibration shall have been performed within the previous two years and after
					 any servicing that may have affected system calibration; or
2. The system shall have been calibrated
					 within the previous four years. 18 to 30 months after that calibration, the
					 system shall have been intercompared with another dosimetry system that was
					 calibrated within the past 24 months by NIST or by a calibration laboratory
					 accredited by the AAPM. The results of the intercomparison shall indicate that
					 the calibration factor of the licensee's system had not changed by more than
					 2.0%. The licensee may not use the intercomparison result to change the
					 calibration factor. When intercomparing dosimetry systems to be used for
					 calibrating sealed sources for therapeutic units, the licensee shall use a
					 comparable unit with beam attenuators or collimators, as applicable, and
					 sources of the same radionuclide as the source used at the licensee's
					 facility.

Current through Register Vol. 40, No. 24, July 15, 2024
A. Each
				  licensee or registrant shall afford to the agency at all reasonable times
				  opportunity to inspect materials, machines, activities, facilities, premises,
				  and records pursuant to these regulations.
B. During an inspection, agency inspectors
				  may consult privately with workers as specified in
				  12VAC5-481-2300. The licensee or
				  registrant may accompany agency inspectors during other phases of an
				  inspection.
C. If, at the time of
				  inspection, an individual has been authorized by the workers to represent them
				  during agency inspections, the licensee or registrant shall notify the
				  inspectors of such authorization and shall give the workers' representative an
				  opportunity to accompany the inspectors during the inspection of physical
				  working conditions.
D. Each
				  workers' representative shall be routinely engaged in work under control of the
				  licensee or registrant and shall have received instructions as specified in
				  12VAC5-481-2270.
E. Different representatives of licensees or
				  registrants and workers may accompany the inspectors during different phases of
				  an inspection if there is no resulting interference with the conduct of the
				  inspection. However, only one workers' representative at a time may accompany
				  the inspectors.
F. With the
				  approval of the licensee or registrant and the workers' representative, an
				  individual who is not routinely engaged in work under control of the licensee
				  or registrant, for example, a consultant to the licensee or registrant or to
				  the workers' representative, shall be afforded the opportunity to accompany
				  agency inspectors during the inspection of physical working
				  conditions.
G. Notwithstanding the
				  other provisions of
				  12VAC5-481-2290, agency inspectors
				  are authorized to refuse to permit accompaniment by any individual who
				  deliberately interferes with a fair and orderly inspection. With regard to
				  areas containing information classified by an agency of the United States
				  government in the interest of national security, an individual who accompanies
				  an inspector may have access to such information only if authorized to do so.
				  With regard to any area containing proprietary information, the workers'
				  representative for that area shall be an individual previously authorized by
				  the licensee or registrant to enter that area.

				  notice, and shall be signed by the worker or representative of the workers. A
				  copy shall be provided to the licensee or registrant by the agency no later
				  than at the time of inspection except that, upon the request of the worker
				  giving such notice, such worker's name and the name of individuals referred to
				  therein shall not appear in such copy or on any record published, released, or
				  made available by the agency, except for good cause shown.

				  occurred. Inspections pursuant to this section need not be limited to matters
				  referred to in the complaint.
C. No
				  licensee, registrant, or contractor or subcontractor of a licensee or
				  registrant shall discharge or in any manner discriminate against any worker
				  because such worker has filed any complaint or instituted or caused to be
