Method for monitoring radioactive cesium concentration in water using cesium adsorption disk and GM survey meter

Nagano, Tetsushi; Mitamura, Hisayoshi; Yanase, Nobuyuki; Naganawa, Hirochika; Yasuda, Kenichiro; Yamaguchi, Hiroaki*

no journal, , 

A method for monitoring radioactive cesium concentration in water using a cesium adsorption disk and a GM survey meter has been developed to ascertain whether the water quality meets standards on radiological contaminants in water. In this method, both dissolved and suspended forms of radioactive cesium are collected on the cesium adsorption disk by means of filtration of a water sample. $$beta$$ count rate of the disk is converted into radioactivity using a conservative calibration factor obtained here. The present method was applied to monitoring of decontaminated water of an outdoor school swimming pool in Date City after Fukushima Daiichi Nuclear Power Plant accident.

Development of time interval analysis for the plutonium monitoring system using $$alpha$$/$$beta$$ surveymeter

Hokama, Tomonori; Fujita, Hiroki; Hashimoto, Tetsuo*

no journal, , 

It is aimed for environmental radiation monitoring to develop the system which detects Plutonium using $$alpha$$/$$beta$$ surveymeter and time interval analysis.
