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. This method was successfully applied to monitoring of decontaminated water of an outdoor school swimming pool in Date City after Fukushima Daiichi Nuclear Power Plant accident.

An on-site monitoring method for radioactive cesium concentration in water using a cesium adsorption disk and a GM survey meter has been developed to rapidly and easily 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 counting rate of the disk is converted into radioactivity using a conservative calibration factor obtained here. The present on-site method was applied to monitoring of decontaminated water of an outdoor school swimming pool in Date city after Fukushima Dai-ichi Nuclear Power Plant accident.

Surface fluorination of PMDA-ODA polyimide has been performed by a hyperthermal F beam. The fundamental properties of the F-beam-exposed polyimide surface are reported based on the analytical results by X-ray photoelectron spectroscopy and contact angle measurements. It was observed that CF, CF
or CF
moieties were formed at the polyimide surfaces depending on the F beam fluences. Advancing contact angles of water can be controlled from 60 to 120 degrees by varying the F beam fluences. Surface roughness analyzed by atomic force microscopy slightly increased with atomic F beam exposures due probably to the formation of volatile products such as CF
. This is confirmed by the mass change during F beam exposure by a quartz crystal microbalance.
