Radon and thoron daughter working levels in British coal mines
Technical Report
·
OSTI ID:5364653
Radon and thoron daughter activity levels were measured for eleven coal mines as a preliminary data collection. Activity was measured from samples of airborne dust particles to which daughter atoms readily become attached. The effects on activity levels of: dust weight and particle size; ventilation distance; atmospheric pressure; and coal rank were investigated. Low levels were recorded in ten of the eleven mines, and ventilation distance was found to be the only factor to exert an effect. It was concluded that in future data collection surveys, account should be taken of ventilation effects.
