作者在福岛医科大学校园进行了数年大气氡、氡子体和氡子体浓度的观测。偶然地，在2005年2月的一个观察学期中，大学的设施管理小组改变了通风方式的策略，可能是因为经济衰退：(1)每天7:30-24:00的整洁通风变成（II）缩短工作日8:00 - 21:00的通风，周末暂停。这种通风方式的改变使室内空气中氡相关天然放射性物质的浓度发生了明显的变化。本文研究了通风策略对室内大气氡相关放射性的影响。
The present author has kept observation for concentrations of atmospheric radon, radon progeny and thoron progeny for several years at the campus of Fukushima Medical University. Accidentally, in the midst of an observation term, i.e., February 2005, the facility management group of the university changed a strategy for the manner of ventilation, probably because of a recession: (I) tidy everyday ventilation of 7:30-24:00 into (II) shortened weekday ventilation of 8: 00-21 : 00 with weekend halts. This change of ventilation manner brought a clear alteration for the concentrations of radon-related natural radioactivity in indoor air. The present paper concerns an investigation of the effect of the ventilation strategy on the indoor-atmospheric radon-related radioactivity.
