R 333.5068 Control of access to very high radiation areas.

Rule 68. (1) In addition to the requirements in R 333.5067, a registrant shall institute additional measures to ensure that an individual cannot gain unauthorized or inadvertent access to areas in which radiation levels could be encountered at 5 grays (500 rads) or more in 1 hour at 1 meter from a radiation machine 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. (2) A registrant is not required to control entrance or access to rooms or other areas containing radiation machines capable of producing a very high radiation area as described in subrule (1) of this rule if the registrant meets all the specific requirements for access and control specified in other applicable parts of these rules.
