The PM1710A Hand-held Gamma and PM1710GNA Gamma-Neutron Monitors are highly sensitive instruments designed to detect and locate even the slightest traces of radioactive and nuclear materials. The PM1710A and PM1710GNA perform the following functions:

Detect gamma and both gamma and neutron radiation, respectively;

 

Locate detected radiation sources;

 

Alert the user of the presence of radioactive or nuclear materials through both audible and vibrating alarms;

Record and store data for up to 1000 events in their non-volatile memory;

Transfer data from the instrument to the PC through an infrared channel.

 

The instruments are easy to use and can be operated even after the minimal training.

Both types of the instruments have a radiation sensitivity that is close to the sensitivity of the much larger and significantly more expensive fixed place pedestrian radiation portal monitors. The PM1710A and PM1710GNA achieve this sensitivity because of their large CsI(Tl) gamma radiation detectors and He-3 neutron detector. However, small and compact ergonomic design of these units allows using these instruments comfortably and easily whether instruments are being carried around or put in a fixed place.

The PM1710A and PM1710GNA are also equipped with an infrared-channel for establishing communication between the instrument and the PC. Through infrared transmission, the user can program the instruments' settings by using the proprietary PC software provided with the instruments. This software also allows the user to download operational data from instruments' memory to a PC for further data processing and analysis.

When the instrument detects radiation that exceeds the preset radiation threshold values, the alarms will begin to signal the danger through either the audible and/or vibrating alarms. The PM1710A and PM1710GNA use an advanced operation algorithm that guarantees rapid detection and localization of the radioactive and nuclear materials even in harsh conditions and environments with variable radiation levels. The rate of the alarm signal series will increase when the instrument approaches the radiation source and will likewise decrease when it moves away from the source, thus allowing a user to locate the radiation source.
