Abstract

PURPOSE: To continuously measure accurate radiant ray density in real time, by locating a plurality of scintillators assembled with radiant ray shield tube different in diameter in measured vessel.
CONSTITUTION: In a cylindrical shape measuring vessel 10 made of copper, gold, and molybdenum less in the adsorption of radioactive substance, a plurality of scintillators 12-1W12-4 are provided along the flow path of fluid sample, and the radiant ray shield tubes 16-1W16-4 different in diameter are located around them. Thus, in measuring the radiant ray density of tritium gas flowing to the vessel 10 continuously, the measurements different in the efficiency are detected from the scintillators 12-1W12-4, and the density of radiant ray of radioactive substance in tritium gas or the like can be made for corrective operation by using the measurements to obtain accurate measurements without various causes to variance.
