Polimaster X-ray and Gamma Radiation Personal Dosimeter Price

product description:

Polimaster’s PM1621 Personal X-ray and Gamma Radiation Dosimeters are professional energy-compensated instruments. This dosimeters monitor and measure the personal dose equivalent Hp(10) and personal dose equivalent rate Hp(10) from both gamma and X-ray radiation. It ability to compensate for the energy variations in the range from 10 keV upto 20MeV allows this personal dosimeters to make extremely accurate measurements.

The dosimeters’ unique characteristics allow users to monitor personal irradiation levels from photon radiation sources, preventing overexposure. The instrument is highly sensitive and can register even the slightest changes in the natural background radiation.

Recommended for the protection of the professionals who work with or around radioactive materials from accidental and unknown radiation exposure, the PM1621 instruments perform the following functions:

Monitoring and measuring the gamma and X-ray dose and dose rate across a wide energy range up to 1 Sv/h (100 R/h);

Alerting the user via 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.

In order to protect the user from overexposure, the dosimeters have two alarm thresholds. If either one of the preset dose or dose rate threshold value is exceeded, the dosimeter immediately alerts the user of the danger via loud, audible alarm. In cases when the radiation intensity exceeds the upper limit of dose rate measurement the LCDs of the dosimeters show the warning sign “OL” followed by the interrupted audible signal.

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.
