Electronic personal dosimeters of PM1610 series provide measurement of dose equivalent (DE) and dose equivalent rate (DER) of continuous and pulsed X-ray and gamma radiation in the energy range from 20 keV to 10 MeV, as well as time of dose accumulation. Instruments have audible, visual and vibration alarms to warn the user when preset dose/dose rate threshold levels are exceeded. Shockproof rubberized case and LCD with fluorescent backlight allows operation in harsh environment. Dosimeters are compact and easy in use, have long life built-in rechargeable battery.
PM1610 series is recommended for use by medical professionals, first responders, customs and border patrol, radiological and radioisotope laboratories, professionals exposed to pulse radiation.
Operation Principle
Dosimeters allow setting of two DER alarm threshold levels and two DE alarm threshold levels. Instruments continuously control the threshold levels and alert the user with audible, light and vibration alarms when the threshold levels are exceeded. Instruments automatically record data into permanent memory and store up to 7500 events of DER and DE measurement history in non-volatile memory.
Modifications available
PM1610 - basic model
PM1610A - modification with extended DE measurement range, relative DER measurement error
Network Functions
Personal Dose Tracker System developed by Polimaster, enables connecting up to 100 units of PM1610. PDT System is intended for continuous account for external radiation exposure, maintenance of dose history database and calculation of the personnel accumulated doses (individual as well as group doses) during the set period of time, alarm when preset thresholds (individual as well as group thresholds) are exceeded. Software enables information transfer by USB-protocol to a personal computer to analyze, process, and generate corresponding databases in a control center or an expert center.
Important
Instrument battery will gradually run down during a long-term storage (even if the instrument is switched off). Over-discharged batteries could lose some capacity. For this reason Polimaster recommends users to charge the battery periodically (at least once per six months).
