Section 157.42. Permanent radiographic installations.

 

(1)   Entry requirements. Each entrance that is used for personnel access to the high radiation area in a permanent radiographic installation shall have either of the following:

(a) An entrance control of the type described in s. DHS 157.26 (1) (a) 1. that causes the radiation level upon entry into the area to be reduced. Entrance control devices that reduce the radiation level upon entry shall be tested monthly.

(b) Both conspicuous visible and audible warning signals to warn of the presence of radiation. The visible signal shall be actuated by radiation whenever the source is exposed or the machine is energized. The audible signal shall be actuated when an attempt is made to enter the installation while the source is exposed or the machine is energized. The alarm system shall be tested for proper operation with a radiation source each day before the installation is used for radiographic operations. The test shall include a check of both the visible and audible signals.

(2)   Device failure. If an entrance control device or an alarm is operating improperly, it shall be immediately labeled as defective and repaired within 7 calendar days. The facility may continue to be used during this 7-day period provided the licensee or registrant implements continuous surveillance and uses an alarming ratemeter. Test records for entrance controls and audible and visual alarms shall be maintained for 3 years.
