Introduction

 

The ASHF Series Gauging System is a projected beam, Cobalt 60 or Cesium 137,  radiation  system and is delivered with one source permanently installed in the shielded section of the unit.  Beam Collimator operation is via pneumatic operator; the tungsten collimator rotates from the fully shielded “OFF” position to the “ON” position in less than one second and returns in less than one second.   The collimator drive system is fully interlocked so that the port cannot be opened unless all interlocks are fully closed.

During all installation procedures, the beam port  is locked in the closed position and there is no possibility of accidental exposure to personnel.  Installation consists of location of the  Unit, complete operational and safety check of the unit, and personnel training.
