The search radiometer SR-5M is designed to detect and localize sources of ionizing gamma radiation, to estimate the radiation dose rate, to indicate the maximum value of dose rate during operation, and to indicate the radiation dose accumulated during the device operation. When additional external sensor connected, it is possible to measure the beta-flux density.
Radiometer high speed of operation allows to make a point source search for gamma and beta radiation. When the operator approaches the source of radiation with increasing dose rate, the readings increase, while the maximum value for the whole measurement time is stored and displayed on the third line of the display. The method of "zoom in-zoom out" allows for 10-20 seconds to localize the source of radioactive emission in the room.
The device is powered by batteries and has a built-in charger.
When powered by a power adapter, the radiometer can continuously be used in the watchdog mode. At the same time, radiometer not only reacts to the crossing of gamma radiation sources into the room but also shows the amount of dose that employees could have received, during the operation of the radiometer.
