Radioactive pollution

Nov 24, 2013· If radioactive waste is disposed of in the appropriate manner then it does not contribute towards radioactive pollution The causes are as follows: Production of nuclear weapons Decommissioning of nuclear weapons Mining of radioactive ore (uranium, phosphate etc) Coal ash Medical waste Nuclear power plants 6...

The Mining Process

The Mining Process The mining process in Florida begins with a field study to determine the location and density of the phosphate deposits Information like the location, size, and shape of the ore is determined to focus the mining effort Hundreds of boreholes are drilled and thousands of core samples studied and tested to gather information ....
