- A. In addition to the requirements in R9-7-420, a 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 1 meter from a source or from any surface that 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 non-self-shielded irradiators.
- B. The 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, described in subsection (A), if the registrant has met all requirements for access and control specified in other applicable Articles, such as Article 5 for industrial radiography, Article 6 for x-rays in the healing arts, and Article 9 for particle accelerators.
- C. Each licensee or registrant shall maintain records of tests made according to R9-7-422(B)(9) on entry control devices for very-high radiation areas. These records shall include the date, time, and results of each test of function.
- D. The licensee or registrant shall retain the records required by this Section for three years after the record is made.
