A warning to anyone who visited Grand Canyon National Park over the last two decades.,
The park’s health and safety manager tells CNN that anyone who visited the park’s museum collections building between the year 2000 and June 18th, 2018, were possibly exposed to unsafe levels of uranium.
The uranium ore in question was found in three buckets stored next to a taxidermy exhibit at the museum.
The national park service eventually removed the buckets last June and disposed of its contents in a nearby uranium mine.
But the manager says the workers who removed the buckets were ill-prepared to do so, and that they returned the buckets to the museum after dumping the ore.
Both the department of interior and a nuclear engineering expert tell CNN that they believe the uranium exposure was unlikely to be hazardous to visitors.
The Department of Interior adds it’s also working with OSHA and state officials to investigate what happened.
