Gauges-signaling search ISP-RM1703M and ISP-RM1703MA - are highly sensitive search compact instruments designed for the detection and localization of radioactive materials
The device has two modes of operation :
search for radioactive sources on their external gamma radiation
assess the level of radiation in mSv / h (through 137Cs collimated radiation ) .
Is turned on or when the user requests the device automatically measures and stores the background radiation in the control zone. Later, he immediately reacts with excess background noise , notifying the sound , light and / or vibration signal for detection of latent or in areas with high noise levels.
This function provides adequate adaptation to changes in the instrument background and simplifies the localization of a radioactive source in a high radiation intensity (localization of a point source on the background distributed radioactive source) .
