Purpose: EXPERT dosimeter-radiometer is meant for identification of photon gamma-radiation equivalent dose capacity and beta-radiation flux density from contaminated surfaces in everyday life.
The device was included into the State Register of Measuring Instruments under No.13603-93
Measuing device type description
CE-sertification is in progress (november-december 2011).
Dosimeter to measure the seafood comes with a plastic bag with a lock.
Peculiarities:
- Capability of working in two independent modes of gamma- or beta-radiation measuring;
- Maintaining digital indication of measuring results on liquid-crystal display;
- Maintaining indication of MEASURING and RESULT operation modes;
- Indication of the source charge supply;
- Maintaining one second audio signal generation at the moment the instrument changes from MEASURING to RESULT mode;
- Maintaining continuous audio signal generation if the dose rate exceeds 99.99 mcSv/ hour;
- the device can be used in SEARCH mode for a radiation source detection.
Main technical characteristics of the device:
- Range of equivalent dose rate measuring, mcSv/hour 0.1-500;
