Hydraulic fracturing and radionuclides - Wikipedia

Hydraulic ,fracturing, is the propagation of fractures in a rock layer by pressurized ,fluid,. Induced hydraulic ,fracturing, or hydrofracking, commonly known as fracking, is a technique used to release petroleum, natural gas (including shale gas, tight gas and coal seam gas), or other substances for extraction. Radionuclides are associated with hydraulic ,fracturing, in two main ways.
