FIELD: measurement technology. SUBSTANCE: procedure includes injection of radiation into sealed cell filled with gas absorbing radiation. Acoustic signals are transmitted through gas absorbing radiation, change of speed of transmission of these acoustic signals through absorbing gas caused by radiation absorption is measured and value of change of speed of acoustic signals is used to determine energy of optical and SHF radiation. EFFECT: raised sensitivity of measurements.
