PM1621/ PM1621M
General Purpose Pocket Dosimeter
The PM1621/PM1621A dosimeters are professional instruments for measurement of personnel dose equivalent Hp(10) and dose equivalent rate Hp(10) of X-ray and gamma radiation within the wide range of energies - from 10 keV to 20 MeV.
Dose rate measurement range for the PM1621 is here 0.05 mSv/h - 0.1 Sv/h, for the PM1621A - 0.05 mSv/h - 1 Sv/h. Such energy range and dose rate measurement range allow to control radiation situation and radiation dose of the user not only when working with sources of ionizing radiation of various intensity but also in conditions of slight natural background's fluctuations.
A function of storage of dose rate history, accumulated dose value and serial numbers of the dosimeters in their non-volatile memory and further transmission of these values to PC through IR-adapter using a software is provided for in the dosimeters. It makes it possible to use the dosimeter as a component of computer system for accounting the doses of personnel and for creating corresponding data bases.
The devices allow the user to preset alarm thresholds on dose rate and accumulated dose (two independent thresholds for dose and two for dose rate, which differ in type of audible alarm signals). In case any of the preset thresholds is exceeded this information is indicated in the LCD and corresponding audible alarm signal sounds. The dosimeters automatically count the time of dose accumulation.
The PM1621M version holds a LED- alarm indication and vibration alarm for loud environments.
Both dosimeters have shockproof hermetic housings thus making it possible to decontaminate it. The dosimeters can be worn both in the breast pocket or attached to the belt
