概要
- 論文の詳細を見る
Application of coal combustion ashes in building materials has been limited by the presence of minor components such as radioactive substances. ^<226>Ra, ^<232>Th, and ^<40>K accumulated in the ash during the burning of the coal may result in significant, several doses of mSv annually. Radon exhalation is usually low, but in some cases a significant dose (5-15mSv/y) may be calculated upon due to the ^<222>Rn emanating from this kind of building materials. Therefore a radiological survey, classification of these materials is necessary before utilization.
