Description

The physical characteristics of alpha-emitting long-lived dust were investigated in uranium mines and mills. The MMAD and AMAD were generally within the range of 2 to 10 μm with standard geometirc deviations between 3 and 5. Radon emanation rates from uranium bearing particles is about 30%. The activity air concentration of alpha emitting dust ranges from 10 to 700 mBq/m3 in underground locations and from 10 to 2000 mBq/m3 in mills
