Abstract

PURPOSE: To enable the measurement through simple selection of the measurement of a weak radioactive level and that of good response, by switching selectively the 1st measuring mode catching the radiant ray with catching material and the 2nd measuring mode measuring the radiant ray in gas directly.
CONSTITUTION: When a detector 1 and a catching material 6 are at corresponding location, the radiant ray in gas suctioned from an absorbing tube 3 is caught in a catching material 6 and the result is measured with a detector 1 and a measuring device 101. Next, by turning a half the detected vessel 8 with a drive means 9, the radiant ray in space formed with spaces 7a, 8b is measured at the detector 1. With this state, the radiant ray is directly measured in gas, then the responsive measurement can be made, if the radiant ray level is over a given level.
