radon concentrations in ore mines of baluchistan

    Radon concentrations in three underground lignite mines in ...

    Sep 21, 2009· The radon gas concentrations in the lignite mines were determined to be between 50 ± 7 and 587 ± 16 Bq m 3. The results obtained in these experiments are far under the action levels. The computed radon doses for the mine workers of Tunçbilek, Ömerler and Eynez lignite mines are 1.23, 2.44 and 1.47 mSv y 1, respectively.

    ber of abandoned mine environments. High radon levels, up to 28589Bqm3, have been measured in parts of one mine. This study demonstrates that industrial archaeologists (such as the Cumbrian Amenity Trust Mining History Society or CATMHS members) and explorers of abandoned mines can be at risk from radon exposure and it proposes a management
