Atmospheric tritium (3H) and radioactive carbon (14C) simultaneous collection devices

摘要

TECHNICAL FIELD The present invention relates to a collecting device for simultaneously collecting tritium present in the atmosphere as a chemical type (water-state tritium: HTO, gaseous tritium: HTO) and simultaneously collecting radioactive carbon.;The configuration includes a pressure regulating pressure regulator 3 for regulating the internal pressure of the collecting device via the dust removing filter 1 and the inflow air control valve 2 from the inlet port side, a flow rate regulating controller 4 for regulating the collecting flow rate, A seasonal change-over switch 8 provided with a moisture removing device, a dehumidifying device water collecting container 10, and a device for collecting tritium by chemical type, A tritium trapping section 11, an oxygen gas generating device 12, an oxygen gas water removing section 13, a gaseous tritium oxidation column 14, a gaseous tritium trapping section 15, The radioactive carbon capture section 18 is installed in series through the pump 16.
