| 内容記述 | Ground and surface water usually contains a certain amount of radionuclides, including radon, which dissolves from rocks and soil into water. The current methods for radon measurement in water are mainly based on active measurement techniques, e.g. the degassing of radon using bubbling in combination with alpha or gamma spectrometry (bubbling method), gamma-ray spectrometry or liquid scintillation counting (LSC). These methods have some disadvantages that include poor resolution (gamma detectors), the influence of water temperature and the level of degassing during transport (bubbling method). Therefore, a passive, cheap and effective method based on CR-39 chips may be a good candidate for wide-ranging of surveys where the transportation of water samples would be troublesome. This method could be used not only for radon protection surveys, but also for geo-hazard research. The present paper describes the validation of the recently developed radon-film-badge for radon measurements in water using RAD7 and LSC methods. A radon-film-badge was constructed incorporating a thin-film radiator (Makrofol-polycarbonate) with suitable radon-sorption characteristics, placed next to a track detector (CR-39), then sealed a polyethylene bag. Different radon-badges were exposed to highly radon contaminated water from a 70 m deep well located in Kobe. The same water was measured using an electrostatic type radon monitor (RAD7) in 250 ml vials, and with the liquid scintillation method (LSC). In addition, the calibration factor for the radon-film-badge in air was obtained at the QST/NIRS radon facility. |
