Abstract

PURPOSE: To improve accuracy of radiation measurement by dividing the path of the liquid to be measured by a shading film to control the Charenkov ray-incidence on the scintillator, which ray is generated in one of the shunt paths whereby the detection error is eliminated.
CONSTITUTION: A scintillator 12 in a radiation detector is disposed by a conductor tube 10 which conducts radioactive-material-containing liquid and the path of liquid to be measured 14 is devided into the first and second shunt paths 18, 20 by shading film 16 which consists of silver or aluminum metallic film. Therefore, the shading film 16 is placed between the first shunt path 18 and the scintillator 12. Cherenkov ray which is generated in the first shunt path 18 is shaded by the shading film 16 and the ray will not reach the scintillator 12. Therefore, the detecting quantity of cherenkov ray is remarkably reduced and the radiation having a wide ranged energy can be measured with high accuracy.
