Abstract
A radioactive gas monitoring device includes a sample chamber into which a sampled gas is introduced; a plastic scintillation detector outputting first detection signal pulses; an inorganic crystal scintillation detector outputting second detection signal pulses; a first measurement unit calculating a first count rate from the first detection signal pulses to output the first count rate, and issuing a first alert when the first count rate becomes higher than a first preset level and issuing a second alert when the first count rate becomes higher than a second preset level higher than the first preset level; and a second measurement unit calculating a second count rate from the second detection signal pulses to output the second count rate, and issuing a third alert when the second count rate becomes higher than a third preset level.
