X-ray and Gamma Radiation Personal Dosimeter РМ1621

PM1621 series dosimeters are professional energy-compensated instruments, which designed to monitor and measure dose equivalent and dose equivalent rate from both gamma and X-ray radiation. Instruments are highly sensitive and register the slightest changes in the natural background radiation. Hermetic and shockproof case and fluorescent backlight on LCD screen allow operation in the harsh and unfavorable environments.

Instruments of PM1621 series are recommended to use by Law Enforcement and Security agencies, scientists, medical and other professionals, exposed to gamma and X-ray radiation.

Operation Principle

Instruments measure gamma and X-ray dose and dose rate at a wide energy range up to 1 Sv/h, alert user via an audible alarm when the preset dose or dose rate thresholds are exceeded. When the radiation intensity exceeds the upper limit of dose rate measurement, the warning sign “OL” (on LCD) and interrupted audible signal appear. Instruments record and store  up to 1000 events (500 DER + 500 DE) in its non-volatile memory, transmit all recorded data via an infrared channel to PC for further processing and analysis.

Instruments can be used independently or as a part of unique operational dosimetry system for everyday and emergency radiation control, tailored to the specific needs of customers.
