FIELD: radiometry, possible use for determining radiation situation in zone where radiation-hazardous industries are located under conditions of normal operation of controlled object and of emergency emissions.
SUBSTANCE: proposed device contained detection device, provided with detector, impulse amplification block, connected to analog-digital conversion block, high voltage and low voltage power blocks and spectrum analyzer, and also analog-digital conversion block. Detection device is located onboard a light aircraft, additionally carrying dosimeter of dose of gamma-radiation absorbed in air and block for contact-free remote information transfer, spectrum analyzer is positioned on ground-based vehicle, provided with block for receiving measuring information, while aircraft and vehicle are provided with blocks for determining coordinates and receiving-transmitting blocks for controlling flight of aircraft, while block for contact-free remote information transfer is connected to outputs of analog-digital converter and dosimeter. Given device realizes corresponding method for remotely determining concentration of radio-nuclides in air emission.
EFFECT: increased sensitivity and precision when determining concentration of radio-nuclides, significant from radiology point of view, in emission of radiation-hazardous industries.
