The tiny personal radiation detectors designed to detect and locate the minimum amounts of the radioactive and nuclear materials. The instrument provides two operating modes: search for the gamma radiation sources and evaluation of the radiation level in mSv/h or mR/h.

Polimaster's Personal Radiation Detectors PM1703M and PM1703MA are designed to detect and locate even the slightest traces of the radioactive and nuclear materials. The instruments' two operating modes enable the user both search for gamma radiation sources based on the intensity of the emitted radiation and evaluate the radiation level.
The PM1703M/MA perform the following functions:
Once the detector is turned on, it automatically starts taking measurements and storing the background radiation information. The personal radiation detectors PM1703M and PM1703MA can detect even the slightest increase in radiation environment that causes the radiation levels to exceed the preset thresholds. The instruments' advanced processing algorithm enables the user to update the background levels and setup the alarm thresholds thus adjusting to the specific radiation environments and satisfy the requirements for the false alarm rate.
The PM1703M/MA are additionally designed to ensure adequate adaptation to the background level so that the instruments can locate a radioactive source in changing environments. For example, the detectors are able to detect radiation sources when the background decreases due to radiation shielding or when the background radiation intensity is high requiring the source to be located among high radiation level.
The PM1703M/MA have a hermetic and shockproof case and the LCD screen's fluorescent backlight for easy operation even in the harshest, most unfavorable environments or weather conditions. The personal radiation detectors are recommended for first responders, security guards, police, customs officers and border patrol. No special experience or training is necessary to operate the instrument.
In addition to the functions of the PM1703M/MA models, the PM1703MB model has Bluetooth module for communication with PDA or laptop PC, equipped with Polimaster proprietary identification software, and can be used for the radioisotope identification of the radiation source.
The Bluetooth module allows user to be at a safe distance from the possible radiation sources while the PM1703MB is operating. In that way, the instrument's operator is being protected from the radiation exposure by distance.
