Dec 02, 2020 Phosphogypsum, a waste product from manufacturing fertilizer, emits radon, a radioactive gas. It also contains the radioactive elements uranium, thorium and radium. Phosphate rock mining is the fifth largest mining industry in the United States

Radiation protection in mining and milling of radioactive ores

have potential for mining and milling of uranium. Some, such a Niger and Gabon, are already mining and milling uranium with the help of foreign uranium mining companies; others have been carrying out active explora­ tion or prospection for uranium or other radioactive ores. Many do not have their own means of ensuring adequate

What is Radioactive Pollution? Causes & Management

Mining of radioactive ore (uranium, phosphate etc.) mining these involves crushing and processing of the radioactive ores and this generates radioactive waste which emits alpha particles. This waste is of low risk unless ingested.

the mining and processing of ores, both as a physical transport medium, and by selective chemical interaction with certain components of the ore. The identification of uranium in Witwatersrand ores dates back to 19151. It was known that uranium was radioactive, but this was not considered to be particularly hazardous. An early reference to a radiation

What are the radioactive minerals currently being mined?

Nov 19, 2018 Canada is the world’s second-biggest producer, accounting for 22% of global production; its Cigar Lake underground operation produced almost 7,000 tonnes of uranium in 2017, 12% of the world’s total production.. However, uranium mining continues to pose a legal problem for many countries; the US Supreme Court is currently considering reversing a long-standing ban on uranium mining in

Multivariate statistical analysis of radioactive variables

May 01, 2012 Highlights Multivariate statistical techniques were used to characterize radioactive data. U-238 in Uro phosphate shows higher degree of mobility (CV% = 82.6). U-238 in Kurun phosphate shows lower degree of mobility (CV% = 64.7). The radioactive variables did not follow a normal distribution. The ratio of Th-230/Th-323 in Uro is nine times than that in Kurun.
