High sensitive personal gamma radiation detectors especially designed to operate in the harsh environment. The detectors are used both for search of the radiation and nuclear materials and evaluation of the radiation level.

The Personal Radiation Detectors PM1401MA are used for detecting and locating gamma radiation sources especially in the extreme environment and the difficult-to-access areas. To protect the user from the radiation sources and inspect difficult-to-access areas, the optional telescopic extension tube is provided.
The PM1401MA performs the following functions:
Once the PRD is turned on, it automatically starts taking measurements and storing the background radiation information. The personal radiation detector PM1401MA can detect even the slightest increase that causes the levels to exceed the radiation background. The instruments' advanced processing algorithm enables the user to update the background levels and setup the alarm thresholds depending on the probability and false alarm rate requirements.
The PM1401MA is additionally designed to ensure adequate adaptation to the background level so that the instrument can locate a radioactive source in changing environments. For example, the detector is 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 PM1401MA has 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 detector is 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 PM1401MA model, the PM1401MB 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 PM1401MB is operating. In that way, the instrument's operator is being protected from the radiation exposure by distance.
