X-ray (continuous/pulsed) and gamma radiation personal dosimeter with an extended range of dose measurement.
PoliSimeter™ series of electronic personal dosimeters (EPDs) is the next generation of the well-known PM1610 series by Polimaster, which was a trusted solution on the market for nearly 15 years, with over 20,000 dosimeters sold. Building on the legacy of the PM1610, the PoliSimeter offers enhanced capabilities for the extended measurement of personal dose Hp(10) and dose rate Ḣp(10) of both continuous and pulsed X-ray and gamma radiation. The PoliSimeter is designed to meet the latest industry requirements and features a USB-C port for convenient connectivity and data transfer.
PoliSimeter ER model has an extended range of dose measurement of up to 20 Sv for use in high-radiation environments, providing critical safety and monitoring functionality.

Operation principle
The PoliSimeter EPDs allow the setting of two dose rate alarm thresholds and two dose alarm thresholds. The instruments continuously control the threshold levels and alert the user with audible, visual, and vibration alarms when any of them are exceeded. PoliSimeter automatically records and stores in its non-volatile memory up to 7500 dose rate and dose measurement history events.
The dosimeter is manufactured in two models: the basic PoliSimeter model and the PoliSimeter ER model with an extended range of dose measurement of up to 20 Sv.
The EPD is supplied with the user software for downloading measurement history to a PC, maintaining the personnel exposure database, and adjusting the settings of the dosimeter. The PoliSimeter dosimeters are also compatible with the Automated Personal Dosimetry System for maintaining the instrument history database and monitoring personnel exposure.
Important: During long-term storage, the instrument battery may gradually discharge even when the instrument is switched off. Over time, deeply discharged batteries may experience a decrease in capacity. To prevent this, Polimaster recommends periodically charging the battery, at least once every six months.
