Abstract

PURPOSE:To enable reliable discriminating of detecting pulse corresponding to a type of incident radiation by means of a simple constitution, by a method wherein a radiation detecting wave form is discriminated based on a difference in luminous attenuating time. CONSTITUTION:Incident radiation has a difference in luminous attenuating time corresponding to beta ray 101, or alpha ray 201, and thereby a pulse 300 from a crest comparison circuit 18 is generated only at a detecating time of beta ray having a short attenuating time resulting from the comparison of a radiation detecting wave form 102 or 202, integrated by an integration circuit 12, with a radiation detecting wave form 103a or 203a processed by an integration circuit 16 and a delay circuit 22. The pulse 300 closes a first output control circuit 28 and opens a second output control circuit 30 to count a radiation detecting pulse from beta ray discriminated by a second counter circuit 34, and a radiation detecting pulse from alpha ray is counted in a similar manner by a counter circuit 32. The employment of a system, in which an attenuating time is not measured but a difference in attenuating time is utilized, permits the reliable discrimination of a detecting pulse by means of a simple constitution.
