Description

Direct reading personal dosimeter in a damp and dustproof body with a high ingress protection rating IP54, designed for use by the Army, Ministry of Emergencies and Civil Defense, and in industry in conditions of significant temperature oscillations and high dustiness of atmosphere.

It can be used either independently or within the automated system of personal dosimetry control.

Purpose of Use

Measurement of individual dose equivalent (DE) of gamma and X-ray radiation
Measurement of individual dose equivalent rate (DER) of gamma and X-ray radiation

Branches of Use

Mining industry

Law enforcement agencies

Emergency Services and Civil Defense

Features

Storage of dose accumulation history in the non-volatile memory with real time reference
Transfer of dose accumulation history through the infrared port to the computer
Blocking the mode of power supply switch off until the data reading procedure finished
Gamma and X-ray radiation DER and DE threshold levels programming with the help of the computer or manually with control keys
Blocking certain indication modes in response to the computer command
Light and audio alarms when programmed threshold levels exceeded on DER and DE of gamma and X-ray radiation
Display automatic switch 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 of batteries and detector
Energy-compensated Geiger-Muller counter
Ingress protection rating IP54
Clock, alarm clock
Software allows to:

– program parameters and operating modes

– read dosimetric measurement results

– review and print dosimetric information as reports

– save and export read information as a report or text file for further processing by other text editors

– import previously stored dosimetric information for processing and analysis
