Detect gamma radiation sources, even when they are shielded;

Alert the user to the presence of a radiation source through audible, visual and vibrating alarms;

Record and store data for up to 1000 events in the instruments' non-volatile memory;

Transmit all recorded data to a PC via IR channel for the data processing and analysis.

 

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.
