Personal gamma radiation dosimeter DKG-21
Purpose of use
Measurement of personal gamma radiation equivalent dose rate (EDR).
Measurement of personal gamma radiation equivalent dose (ED).
Clock, alarm clock.
Application
The dosimeter may be used at atomic power engineering sites, physics laboratories, health care organizations as an electronic dosimeter for automated systems of personal dosimetry control ASPDC-21, and as an independent device.
Features
Stand-alone use or use within the automated system of personal dosimetry control.
Dose accumulation history storage in the nonvolatile memory with real time reference.
Dose accumulation history transfer to the computer through infrared port.
Locking power down mode of the dosimeter until all accumulated data read.
Gamma radiation EDR and ED threshold levels programming with the help of the computer, control keys, or manually.
Blocking certain indication modes with the help of the computer command.
Light and audio alarm of exceeded programmed threshold level of gamma radiation EDR and ED.

Digital display automatic switching-off if current gamma background is lower than the preset threshold level with instant switching on at:

- pressing any control key;
- gamma background increase above the preset threshold level;
- alarm clock ringing.
Periodic self testing (batteries, detector).
Energy compensated Geiger-Muller counter.
