Analysis device for the detection of fission products by measurement of a radioactivity

摘要

An analysis device (10) for the detection of fission products by measurement of a radioactivity includes a first line (12) for carrying a liquid sample, a first detector (17) connected to the first line (12) and designed for measuring the radioactivity of fission products contained in the liquid sample, a second line (23) for carrying a gas sample and a second detector (29) connected to the second line (23) and designed for measuring the radioactivity of fission products contained in the gas sample. The analysis device includes a separation device (18) for separating gas from the first line (12) carrying the liquid sample, which line has an outlet opening into the second line (23) for removed gas in such a manner that the removed gas can be supplied as a gas sample to the first detector (17) for measuring the radioactivity of fission products contained therein.
