MINOT, N.D. - State officials say bags of hydraulic fracturing sand stored at a downtown Minot site do not pose a health risk to the public.
The sand is used in the recovery of oil from shale rock. The state Health Department tested the Minot material in the wake of municipal landfills in western North Dakota rejecting some oil field waste because of elevated radiation levels.
Health Department program manager Dan Harman said the level of radioactivity in the Minot tests was far below what most people encounter in nature on a daily basis. He says radioactive readings were so low they could not be measured by standard Geiger counters, and more specialized equipment had to be used
