摘要

Forty-one measurements of indoor radon concentration were carried out in eleven play schools and five kindergartens of Parma (northern Italy) in the period autumn 1994- spring 1995. Radon measurements were made with Solid State nuclear Tracks Detectors (SSNTDs), which were placed in rooms where the children spent most of the time. Forty-seven addition measurements were performed in the selected buildings by means of Radon on Activated Charcoals (ROACs). The collectors were exposed (one for each story) for about 48 h in October of 1994, and a second screening was repeated in January of 1995.
