Professional individual 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.
 |
Polimaster's PM1604A and PM1604B models are miniature energy-compensated personal dosimeters that measure personal dose equivalent Hp(10) and personal dose equivalent rate Hp(10) of both gamma and X-ray radiation.
Recommended for use by professionals who work with or around the radioactive materials. The PM1604A and PM1604B perform the following functions:
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.
