| Research Abstract |
Radon concentration change in a closed room was investigated to give quantitative knowledge on quantitative properties of radon exhalation from building materials, in order to develop an education program on natural radioactivity in a university. The project includes quantitative studies on "monitoring of radon concentration in a closed room", "determination of Ra-226 in building materials", "collection of radon progenies using a glass filter", "exhalation properties of radon from building materials (effect of temperature, moisture)".
