Examining Uranium Mining in the Canyon Mine

Health in Uranium Mining

Safety in mining radioactive ores, and in milling and treating them, has been a serious preoccupation for some thirty years. Much earlier than this, however, a high incidence of lung cancer had been reported among the miners of the Erzgebirge mountains in the German-Czechoslovak border region (places familiar under the names of Schneeberg and St. Joachims thai). Investigations into deaths from ...

Feasibility of Uranium Concentration Measurements for H Canyon Tank 16.7

SRTC evaluated the feasibility of using the H Canyon on-line diode array spectrophotometer to measure uranium concentrations in Tank 16.7. On-line measurements will allow an increase in highly enriched uranium (HEU) production by removing delays associated with off-line measurements. The instrument must be able to measure uranium at concentrations below 1.0 g/L with an uncertainty no greater th...

Recalibration of H Canyon Online Spectrophotometer at Extended Uranium Concentration

Uranium mining and health.

The energy needs of our society are becoming a challenge. One energy source, nuclear power, is entirely dependent on uranium. Increasingly, physicians are opposing the mining of uranium. In the 1980s, family physician Dr Robert Woollard led a task force that resulted in a provincial moratorium on uranium mining in British Columbia.1 In autumn 2009 in Sept-Îles, Que, more than 20 physicians thre...

Eukaryotic life in biofilms formed in a uranium mine

The underground uranium mine Königstein (Saxony, Germany), currently in the process of remediation, represents an underground acid mine drainage (AMD) environment, that is, low pH conditions and high concentrations of heavy metals including uranium, in which eye-catching biofilm formations were observed. During active uranium mining from 1984 to 1990, technical leaching with sulphuric acid was ...
