X-ray (continuous/pulsed) and gamma radiation personal dosimeter.
The PM1610 series of electronic personal dosimeters (EPDs) are intended for measurement of the personal dose equivalent Hp(10) and personal dose equivalent rate Ḣp(10). The dosimeters are suitable for multiple applications providing the measurement of X-ray (continuous and pulsed) and gamma radiation in the wide energy range.
The PM1610 dosimeters have unique features for operation in workplaces requiring the use of personal protective equipment or in a harsh environment, including a shockproof rubberized case, a high contrast display with a fluorescent backlight, and two big buttons for easy use even while wearing protective gloves.

Operation principle
The PM1610 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. PM1610 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 PM1610 model and the PM1610A model with an extended dose measurement range of up to 20 Sv and improved accuracy of the dose rate measurement.
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 PM1610 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.
