Area II is expected to remain active through the life of the mine. Sand-clay mix will be deposited over most of the mine site (3915 acres of the 4591 mined). Sand-clay mixing ratios ranging from 1.9:1 to 3.1:1 sand to clay are planned, depending primarily on the relative proportions of sand and clay generated by the beneficiation process.

Radon - Reduction Guide for Canadians - Canada.ca

Radon is a radioactive gas that you cannot see, smell or taste and can get into your home undetected. It is the second leading cause of lung cancer after smoking and the leading cause of lung cancer for non-smokers. When radon escapes from the ground into the outdoor air it is diluted to low concentrations and is no cause for concern.

Radiation Basics | US EPA

Jun 24, 2022Ionizing radiation has so much energy it can knock electrons out of atoms, a process known as ionization. Ionizing radiation can affect the atoms in living things, so it poses a health risk by damaging tissue and DNA in genes. Ionizing radiation comes from x-ray machines, cosmic particles from outer space and radioactive elements.

Acid rain - Wikipedia

Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH ). Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4-5 on average. [1] [2] The more acidic the acid ...
