Wheeler River mining project gets go-ahead
Canada’s first in situ recovery (ISR) uranium mining operation has been granted final regulatory approval. Toronto-based Denison Mines Corp. announced last week that the Canadian Nuclear Safety Commission has approved the environmental assessment and issued the license to construct a mine and mill for the company’s Wheeler River uranium project, located in northern Saskatchewan’s Athabasca basin. This project, which includes the Phoenix uranium deposit, previously received the necessary provincial approvals.

The two media method used to determine the linear attenuation coefficients of irregularly shaped samples without the knowledge of the thickness of the sample has been verified. The linear attenuation coefficient values of regularly and irregularly shaped flyash material samples have been measured by the two media method using five different materials as media. The obtained values of the linear attenuation coefficient were compared with the results of the standard narrow beam gamma-ray transmission method. The results were in good agreement.
