PM1621 is a sensitive X-Ray and Gamma Personal Dosimeter equipped with a GM tube.
PM1621 is a professional energy-compensated instrument. This dosimeter monitors and measures the personal dose equivalent Hp(10) and personal dose equivalent rate Hp(10) from both gamma and X-ray radiation. Its ability to compensate for the energy variations in the range from 10 keV up to 20MeV allows it to make extremely accurate measurements.
Its unique characteristics allow users to monitor personal irradiation levels from photon radiation sources, preventing overexposure. The PM1621 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, as well as for medical staff, the PM1621 instrument performs 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 in their non-volatile memory;
– Transmitting all recorded data via an infrared channel to a PC for further processing and analysis.
