Gamma search devices in a robust metal case. The devices are specially designed for use in harsh field conditions.
ISP-PM1401MA
The ISP-PM1401MA search meter and alarm is a highly sensitive compact search device designed to detect and localize radioactive materials. The device has two operating modes: searching for radioactive sources by their external gamma radiation and assessing the radiation level in μSv/h (along the 137Cs line in collimated radiation).
Main features:
CsI(Tl) scintillation detector;
Built-in sound and light alarm;
External vibration alarm;
Non-volatile memory;
Communication with a personal computer via an infrared channel;
Metal shockproof case;
Light weight and small size;
Ease of use.
When switched on or at the user's command, the device automatically measures and stores the radiation background in the control zone. In the future, it immediately responds to even a slight excess of the background value, notifying about it with a sound, light and/or vibration signal for hidden detection or work in places with an increased noise level. This function ensures adequate automatic adaptation of the device to a change in the background level and simplifies the localization of the radioactive source in conditions of increased study intensity (localization of a point source against the background of a distributed radioactive source).
The algorithm used in the ISP-PM1401MA search meter-alarm allows the user to change the value of the preset threshold depending on the requirement for the frequency of false alarms and the probability of detecting the radiation source.
The device's volatile memory stores the history of its operation, including the fact and time of response, the level of its excess in relation to the set threshold, as well as information on the state of the parameters of the meter-alarm. This information can be transferred to a personal computer via an infrared communication channel for further processing, analysis and control.
The measuring and signaling device is easy to maintain, and special qualifications and user training are not required for correct operation of the device. The device can also be supplied with a telescopic extension designed for radiation monitoring in hard-to-reach places and providing higher radiation protection for the user.
ISP-PM1401MA-01 In addition to the functions of the basic model ISP-PM1401MA, ISP-PM1401MA-01 can also be used for primary radioisotope identification. ISP-PM1401MA-01 is equipped with a Bluetooth module for wireless remote information exchange between the radiation detector and a pocket personal computer (PPC) or laptop. ISP-PM1401MA-01 accumulates the gamma spectrum of the detected source and transmits it via Bluetooth to the PPC for spectrum analysis and radioisotope identification using specially developed PoliIdentifyTM software. The Bluetooth module and the two-component (radiation detector and PDA) design allow the user to remain at a safe distance from the radioactive source during operation. This provides an additional level of protection for personnel conducting radiation investigations.
