Radon concentration and radiation exposure due to radon daughter products in non-uranium mines in the EC, and factors of influence

Description

A number of nine mines representing a variety of underground structures and ventilation systems have been examined. The personnel underground differed in number from only a few to some hundred miners. The results measured for radium-226 are between 2 and 130 Bq/kg, for thorium-228 between 2 and 74 Bq/kg, and for potassium-40 between 30 and 950 Bq/kg. The fluctuations of radon-222 concentrations in a given mine are obviously correlated with the ventilation conditions. (orig./PW)

Abstract (German)

Es wurden insgesamt neun Bergwerke mit unterschiedlichen Grubengebaeuden untersucht. In der Bewetterung waren ebenfalls grosse Unterschiede vorhanden. Die Anzahl der unter Tage Beschaeftigten schwankt zwischen wenigen Personen und mehreren hundert Bergleuten. Die Werte fuer Radium-226 liegen in der Groessenordnung von 2-130 Bq kg-1, fuer Thorium-228 zwischen 2 und 74 Bq kg-1 und fuer Kalium-40 zwischen 30 und 950 Bq kg-1. Die Schwankungsbreite der Radon-222 Konzentration innerhalb einer Grube laesst sich gut mit den Einfluessen der Bewetterung korrelieren. (orig./PW)
