Fracking is being considered once more in New Brunswick and is already practiced elsewhere. But did you know about the radiation risks?
Radionuclides associated with hydraulic fracturing are man-made radionuclides which are used in the hydraulic fracturing process as radioactive tracers or naturally occurring radionuclides released by this process. Injection of man-made radioactive tracers, along with the other substances in hydraulic-fracturing fluid, is often used to determine the injection profile and location of fractures created by hydraulic fracturing.
In addition, hydraulic fracturing releases naturally occurring radioactive materials (NORM) from shale deposits, and these substances return to the surface with wastewater. Concerns have been expressed over the potential health and environmental impact of these materials. Wikipedia
