Radioactive Pollution from the Marcellus Fracking Site

Many pollutants are produced from the fracking process, including chemicals that contaminate the wetlands and soil surrounding the site. In addition,  groundwater contamination from leaks, spills, or ineffective processing can add to increased detrimental effects in the environment. Unfortunately, radiation increases are largely ignored when the risks of fracking are discussed.

Hydraulic fracturing has a strong potential of concentrating the already existing radionuclides, making them accessible to human contact either through disposal or handling. In the 1980s, at other gas drill sites, higher concentrations of radioactivity presented concerns about site workers and the general public when dealing with disposal and by-products from the process.

Type of Radiation Danger from Fracking

What kind of radiation is a danger, when releasing natural gas through the hydraulic fracturing process? The prime suspect is Radium-226. Abundant in gas-producing shale, Radium-226 is formed when the natural Uranium-238 decays in the environment. An alpha-emitter with a gamma ray, Radium-226 has a half-life of 1600 years, and is found in rock, soil, water, plants, animals, and human life, at very low levels. The decay product of radium is radon, another biological hazard with a long list of health issues attached to it.

Radium is soluble in water, and is carried easily by the large volumes of water that are used as part of the hydro-fracking process. A build-up in pipes and on equipment could increase radiation levels, and pose a risk to the workers. Filters in the treatment facilities can also concentrate the radioactive material.  Studies performed on the Marcellus shale through core samples and analysis of the process show that the amount of radioactivity is 20 times higher than background and would be concentrated through the process. The cleanup technology has also been in question. Congressman Tim Bishop, representing the 1st district of New York, released a statement in November, 2011. In part, Congressman Bishop notes,

“H0w can systems designed with technologies to treat domestic sewage and nutrients be expected to safely remove industrial chemicals and naturally occurring radioactive materials from the wastewater stream?”

Risks From Hydro-Fracking

Increased radiation levels from the hydro-fracking system and cleanup have the potential of posing a severe health risk to the surrounding population and site workers. Risks are the result of the concentration of Radium-226. Radium-226 and its decay product, radon, can affect individuals topically and through inhalation and ingestion of contaminated water. With so much unrest on this subject, more research is required to allay health fears and concerns.
