PROTECTION UNIT OF A SURVEY METER AND HIGH RANGE GAMMA RAY SURVEY METER INCLUDING THE PROTECTION UNIT

摘要

Provided is a protection part for an electronic circuit of a survey meter and a high range gamma-ray survey meter into which the protection part is inserted, in which the protection part is easily mounted in the survey meter to prevent the electronic circuit from being short-circuited when a conductive material is introduced into the electronic circuit. To this end, the protection part includes an insulator part for interrupting electricity other than that used for a signal transmission cable, an elastic stainless steel sheet part inserted into the insulator part, and a cable hole part through which the signal transmission cable passes when the protection part is inserted into the high range gamma-ray survey meter. Also, the protection part is inserted into the high range gamma-ray survey meter such that a telescopic part hole and a display part of the high range gamma-ray survey meter are physically separated from each other.
