Iowa Code r. 641-40.43 - Control of access to very high radiation areas
(1) In addition to the requirements in
641-40.42 (136C), 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 500 rad (5 Gy) or more in 1 hour at 1 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 non-self-shielded
irradiators.
(2) 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 as
described in 40.43(1) if the registrant has met all the specific requirements
for access and control specified in other applicable chapters such as
641-Chapter 45 for industrial radiography, 641-Chapter 41 for X-rays in the
healing arts, and 641-Chapter 41 for particle accelerators.
