Abstract：
:The practical application study of a time-integrated radon progeny monitor developed by the authors was carried out in and around a closed uranium mine site during several years. The validity of the monitoring with the monitor was confirmed by good agreement with the other monitoring results and our previous investigations. Radon progeny concentrations were almost at same level outside the site and were within the range of those at controls. The fact shows directly the effect of the mine site on the effective dose to people in outside region is negligible. The F value outdoors in rural area around Ningyo-toge is approximately 0.4 on the whole, while the lower values were observed on the site or near the site, and the higher values, closer to 0.6 in UNSCEAR reports, were observed in the large population areas.
