PCT No. PCT/EP96/00394 Sec. 371 Date Dec. 2, 1996 Sec. 102(e) Date Dec. 2, 1996 PCT Filed Jan. 26, 1996 PCT Pub. No. WO96/24072 PCT Pub. Date Aug. 8, 1996The present invention relates to an apparatus and a method for measuring tritium specific activity by gas scintillation. The specific activity is measured when the tritium is mixed in carrier streams of certain gases which serve as scintillation detection media. The apparatus comprises a detection chamber with connections for gaseous inlet and outlet, the detection chamber being optically connectable to at least one UV photomultiplier tube, which tube is connectable to means for measuring photon emittance.
