Based upon this review, we have concluded that Congress intended in the RECA to compensate uranium miners whose lung cancer "more likely than not" was caused by exposure to radon and its decay products during employment in underground uranium mines. 28 In the statistical terms employed by the BEIRIV and NCI analyses, this standard is equivalent to a probability of causation (PC) equal to or .
and weapons. By the New Stone Age,humans had progressed to underground mining in systematic openings 2 to 3 ft ( to m) in height and more than 30 ft (9m) in depth (Stoces,1954). However,the oldest known underground mine,a hematite mine at Bomvu Ridge,Swaziland(Gregory,1980),is from the Old Stone Age and believed to be about 40,000 years old.
Sep 02, 2010· Workers at Uranium Mine Source Term The radon emanation rate from the Jabiluka ore deposit in Australia was determined at 15 Bq/m 2 ·s per %U 3 O 8 (18 Bq/m 2 ·s per %U) ore grade [Sonter2000]. For secular equilibrium of the uranium series nuclides, this corresponds to Bq/m 2 ·s per Bq Ra226 /g.. Exposure of Miners
None so more than the hardrock underground industry. What do we mean by hardrock? We are talking about gold and rare earths such as lithium, nickel, uranium, and copper to name just a few. At the moment, Australia is on the cusp of another mining boom, specifically in the hardrock mining industry.

accidents related to substandard work at the mine. This was done in order to identify the root causes of substandard practices in the underground working environment and the effects on safety performance. The findings of the study at the mine were compared to those of a cultural study that was completed at mines in a different mining region.
Radon daughter sampling is required for all underground mines. At least one sample from the exhaust air must be taken. Mine operators can request that this sampling be completed by MSHA (30 CFR §§ ). Uranium Mines If the concentration is less than WL in the initial exhaust air sample, sample exhaust air at least monthly.
Compulsory Training Programs for Miners. Most mining countries mandate that each mine have an approved worker training program in health and safety issues. Each plan must include a certain quantity of hours of basic safety training for new miners with no experience. In addition to new miner training, each miner must receive regular refresher safety...
