  • Page 19: Principle Of Operation

    2.1.1.3 PRINCIPLE OF OPERATION 1. Gamma rays and beta particles from radioactive source travel in all directions. 2. Two G-M detectors in the survey meter produce electrical signals when exposed to gamma rays and beta particles. 3. Survey meter converts signals into dose rates and accumulated dose; activates alarm when preset alarm levels are exceeded.
  • Page 20 4. Control panel switches permit operator to set alarm levels for audible or visual display, select display readings and perform equipment tests. 5. Display shows dose rate and accumulated dose values, alarm set levels, battery conditions and test and fault indicators.

  • Page 21: Operation

    GROUND RADIOLOGICAL RECONNAISSANCE (GRR) GRR is the process of detecting radiation and measuring it before a unit moves into or through an area. Note: When the ADM300 is vehicle mounted, a power converter module available to utilize vehicle power.

  • Page 22: Survey And Monitoring Modes

    In the survey or monitoring modes the operator wears the survey meter using the shoulder carrying strap. The ADM300 must be held in at a consistent angle to assure accuracy and uniformity of readings. If the Gun Handle is used, the survey meter can be held more comfortably.

  • Page 23: Beta Monitoring

    The ADM300 is intended for beta radiation detection only. The dose rate indicated is not accurate for beta radiation. When monitoring for beta radiation, the unit must be hand held, and the beta window cover must be open and pointed towards the beta radiation to allow beta particles to enter the window of the low range detector.
  • Page 24 To indicate problems other than low batteries discovered during automatic testing, the general fault indicator (FAILURE) is displayed. If the ADM300 displays the failure indicator during operation, immediately turn the unit OFF and return to maintenance for repair. DELAYED GENERAL FAULT INDICATOR For low-range detector failure, the general fault indicator (FAILURE LOW RANGE) is displayed.

  • Page 25: Operating Procedures

    2.2.3 OPERATING PROCEDURES 2.2.3.1 BATTERY INSTALLATION Note: Only one battery required for operation. Two battery operation recommended. 1. Be sure the ADM300 is turned OFF (display blank). 2. Loosen, but do not remove captive screw.
  • Page 26 3. Open battery well cover and remove two batteries by pulling on the battery compartment pull tab. 4. With pull tab pushed back into battery compartment, insert new batteries (two) into the battery box using the directional label located inside the battery compartment.
