Assessment of dose during the life cycle of natural stone production.
The environmental impact during the life cycle of natural stone production was studied. One of the points of interest was radiation. Natural stone samples from 23 quarries were surveyed for the radioactivity. One quarry was selected for a case study where the effective dose to the workers was assessed. The use of these stones in buildings was also evaluated with respect to the excess dose caused to the residents. According to the results the excess effective dose to the workers does not exceed 1 mSv a(-1) at the quarries. In buildings, all natural stones studied can be used safely as surfacing materials.
