Abstract:Summary Forty-seven measurement of radon concentration were made in some schools of Parma, Reggio Emilia, Albinea and Borzano. The method used was that of activated carbon canisters, which were placed in classrooms, laboratories, libraries and headmaster's offices for at least 48 hours in the period November '90–March '91. It was possible to determine the amount of radon in each canister counting the Pb-214 and Bi-214 gamma emitters by means of NaI (Tl) and Ge (I) detectors. The mean radon concentrations were: 20 Bq/m3 in Parma; 24 Bq/m3 in Reggio Emilia; 46 Bq/m3 in Borzano and 52 Bq/m3 in Albinea. The values recorded in schools are similar to the values previously recorded in dwellings of Parma and Reggio Emilia.
