1.1 Introduction
The Primalert 10 is a compact monitor providing a dependable, continuous means of monitoring radiation
levels and alerting personnel to hazardous conditions. If a therapy system malfunctions, it’s controls may
falsely indicate a safe condition even though the source/beam is on, posing a threat of excessive
radiation exposure to the therapist and technician.
The Primalert 10 monitor is activated when the radiation level exceeds a preset value. The alarm level
(2.5 mR/h or 20 mR/h) is selected by means of a slide switch on the front panel. A pair of bright red lamps
on the face of the instrument flash a warning and continue to flash until safe conditions are reestablished.
Since the system can be activated by scattered radiation, it may be mounted anywhere in the radiation
therapy room. A flashing green OPERATION INDICATOR light continuously monitors the background
radiation and provides visible proof that the instrument is functioning. In high radiation fields (over 100
R/h), the unit will not jam and will continue to alarm.
The Primalert 10 also has a jack for attaching an optional remote Primalarm™ (Model 05-434) at a
location up to 100 feet from the main unit. The Primalarm provides audible and visual warnings of an
alarm condition.
