Gamma Radiation Monitor
Model-P
Purpose
 | The INC Model-P is a radiation area monitor designed to alert personnel to
radiation exceeding selected levels. This alarm system provides indication of radiation
levels at areas such as transportation docks, storage sites, nuclear medicine
facilities, laboratories, industrial centers and radiography installations. |
Description
| When the radiation intensity exceeds a pre-set level, the green light goes out and the
red light and buzzer begin to flash at a one second rate. The alarm is pre-set to trip at
2 mR/hr (user adjustable). Both the high voltage supply for the Geiger tube as well as the
low voltage power supply employ voltage regulation for maximum stability. |
Adjustment
| The sensitivity adjustment is the control mounted on the printed circuit board
(screwdriver adjust). Turning this control CW increases the sensitivity. DISCONNECT
POWER BEFORE REMOVING COVER OR ADJUSTMENT. |
Wall Mount
| Remove the cover and screw the hardware into the wall through the large mounting holes
at each end of the box. |
Spare Lamps
| Two spare lamps and a spare fuse are located inside the alarm box. |
