A PORTABLE SURVEY METER FOR MEASURING THE RADIOACTIVE CONTAMINATION IN EARTH

摘要

The present invention relates to a portable large-area survey meter for measuring the radioactive contamination of a nuclear facility site and surrounding soil and, more specifically, to a portable large-area survey meter for measuring the radioactive contamination of soil, which has an accommodating part with a guide groove to detachably install, on a movable survey meter body, an alpha ray detection kit, a beta ray detection kit, and a gamma ray detection kit for detecting an alpha ray, a beta ray, and a gamma ray emitted from the soil, respectively so as to easily perform a radioactive contamination measuring survey of the soil and which measures radioactivity in real time while moving in a field without the hassle of sampling for a large-area site so as to increase efficiency.
