PM1703MA Personal Radiation Detector

Polimaster's PM1703M series of Personal Radiation Detectors are designed to detect and locate even the slightest traces of radioactive and nuclear materials. The instruments' two operating modes enable the user to search for gamma radiation sources based on their external radiation and then also to evaluate the radiation level.

Recommended for first responders, security guards, police, customs officers and border patrol, no special experience or training is necessary to operate the instruments. The PM1703M series of instruments perform the following functions, they each:

  • Detect gamma radiation sources, even when they are shielded
  • Alert the user to the presence of a radiation source through both audible and vibrating alarms
  • Record and store data for up to 1000 events in the instruments' non-volatile memory
  • Transmit all recorded data via an infrared channel for data processing and analysis

Once the instrument is turned on, the instrument automatically begins taking measurements and storing the background radiation information. The instruments 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 modify the alarm thresholds depending on the requirements to avoid false alarms and the probability of detecting a source.

The PM1703M series is 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 instruments can detect radiation sources when the background decreases due to radiation shielding or when the radiation intensity is high requiring the source to be located among high radiation.

Each of the models is intended for easier and more comfortable operation with their ergonomic, small and light-weight design. Additionally, the PM1703M, PM1703MA and PM1703MB's hermetic and shockproof case and the LCD screen's fluorescent backlight allow for easy operation and precision even in the harshest, most unfavorable environments or weather conditions.


The PM1703MA complies with standard requirements for ANSI N42.32: The American National Standard Performance Criteria for Alarming Personal Radiation Detectors for Homeland Security.
