Sec. 36.29  Radiation monitors.

    (a) Irradiators with automatic product conveyor systems must have a 
radiation monitor with an audible alarm located to detect loose 
radioactive sources that are carried toward the product exit. If the 
monitor detects a source, an alarm must sound and product conveyors must 
stop automatically. The alarm must be capable of alerting an individual 
in the facility who is prepared to summon assistance. Underwater 
irradiators in which the product moves within an enclosed stationary 
tube are exempt from the requirements of this paragraph.
    (b) Underwater irradiators that are not in a shielded radiation room 
must have a radiation monitor over the pool to detect abnormal radiation 
levels. The monitor must have an audible alarm and a visible indicator 
at entrances to the personnel access barrier around the pool. The 
audible alarm may have a manual shut-off. The alarm must be capable of 
alerting an individual who is prepared to respond promptly.
