Personal radiation detector PM1401MA is designed for detecting of gamma radiation sources. Due to its hermetic and shockproof case and the LCD screen fluorescent backlight, instrument can be used in extreme and harsh environments. For work in difficult-to-access areas telescopic extension tube is provided. PRD has audible, visual and vibrating alarms, records and stores up to 1000 events in non-volatile memory and transmits data to a PC via USB interface.
PM1401MA is recommended for first responders, security guards, police, customs officers and border patrol. No special experience or training is necessary to operate the instrument.

Operation Principle
Once the PRD is turned on, it automatically starts taking measurements and storing the background radiation information. Instrument can detect the slightest increase in 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. 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.
