Electronic Personal Dosimeters PM1604/A/B

Mô tả ngắn:Professional individual pocket dosimeters for continuous monitoring of the radiation environment as well as measurement of gamma and X-ray radiation dose and dose rate in the wide dose and dose rate ranges.


Chi tiết:
 Polimaster's PM1604A and PM1604B models are energy-compensated personal dosimeters of pocket size that measure personal dose equivalent Hp(10) and personal dose equivalent rate Hp(10) of both gamma and X-ray radiation.

Pocket dosimeters are recommended for use by professionals who work with or around the radioactive materials. The PM1604A and PM1604B perform the following functions:

  • Monitoring and measurement of the ambient dose equivalent and ambient dose equivalent rate across wide energy range: from the natural background level up to 5-10 Sv/h (500-1000 R/h);
  • Alerting the user through an audible alarm when the preset dose and/or dose rate thresholds are exceeded;
  • Recording and storing data for up to 1000 events (500 DER + 500 DE) in their non-volatile memory;
  • Transmitting all recorded data via an infrared channel to a PC for further processing and analysis.


To protect users from overexposure, the dosimeters have two alarm thresholds. If the preset dose and dose rate thresholds are exceeded, the dosimeter immediately alerts the user of the danger of irradiation through an audible alarm.

The instrument's hermetic and shockproof case and the fluorescent backlight on LCD screen allow for easy operation and precision even in the most harsh and unfavorable environments or weather conditions.

If the dosimeter is contaminated with radioactive dust, it can be easily cleaned with radiation decontamination solutions.
