Abstract

Two radon stations operated for one year (1997) in Lombardy: one was sited in the town of Milan, the second was housed in the EMEP station in the Joint Research Centre at Ispra on Lake Maggiore, north of Milan. The radon concentration was measured hour by hour in both stations. The measurements are obtained by means of a high-volume alpha particle detector which directly gives radon concentration. The radon detector is described. The results of the campaign over the whole year are reported and discussed. The measurements of radon concentration in the atmosphere allow to study the behaviour and the structure of PEL. In partic
