Section 790. Control of access to very high radiation areas

A. In addition to the requirements in 12VAC5-481-780, the licensee or registrant shall institute measures to ensure that an individual is not able to gain unauthorized or inadvertent access to areas in which radiation levels could be encountered at 5 Gy (500 rad) or more in one hour at one meter from a source of radiation or any surface through which the radiation penetrates. This requirement does not apply to rooms or areas in which diagnostic X-ray systems are the only source of radiation, or to nonself-shielded irradiators.

B. The licensee or registrant is not required to control entrance or access to rooms or other areas containing sources of radiation capable of producing a very high radiation area as described in subsection A of this section if the registrant has met all the specific requirements for access and control specified in other applicable parts of these regulations, such as Part V (12VAC5-481-1170 et seq.) for industrial radiography, Part VI (12VAC5-481-1580 et seq.) for X-rays in the healing arts, Part IX (12VAC5-481-2140 et seq.) for particle accelerators, and Part XII (12VAC5-481-2660 et seq.) for irradiators.
