Title Radon and radon daughter concentration in tunnels
Original title Radon und Radonfolgeprodukte in Tunnels und Stollen [in German]
Bibliographic information Schweizerische Unfallversicherungsanstalt, Luzern, Switzerland, Apr. 1976, No.4, p.95-138. Illus. 6 ref.
Abstract Workers in tunnels may be exposed to radiation due to radon or its daughters. Studies in various tunnels and galleries in Switzerland showed that whenever ventilation was provided the radon daughter concentration was below the maximum permissible level of 0.3WL. Higher concentrations were found only in 2 cases: a uranium mine which had for a long time been without ventilation, and a water-feed tunnel in which the ventilation system had been removed after tunnelling had been completed.
