Description

PA-100/M, Detector for Alpha Radiation Only

The PA-100 is an alpha detector and as an external sensor for a ROTEM RAM R-200 radiation survey meter it was designed for monitoring of alpha contamination only.
The detector does not react to beta or gamma radiation at all.
The detector contains a highly efficient air proportional sensor and electronic circuits.
The RAM DA 2000 monitor supplies power and output is a rate proportional to the radiation contamination.
The detector has a low background count rate and is easy to decontaminate.
The sensor contains atmospheric cells made of aluminum containing a thin anode wire.
The surface of the cell is a membrane of aluminized Mylar, protected by a fine stainless steel wire mesh.
 
The detector contains a high voltage power supply, calibrated discriminator, linear pulse amplifier,
pulse shaper, GM saturation indicator, and detector identifier and malfunction detection circuitry.
This configuration minimizes noise, improving sensitivity and stability.
The detector also holds a replaceable cartridge filled with hygroscopic silica gel for the reduction of humidity in the sensor.
