Grand Canyon Visitors May Have Been Exposed To Radiation For Years

joeflies writes: Park safety manager Elston Stephenson provides details about buckets of uranium that exposed visitors to radiation, and the subsequent cover up. The radiation was detected by a teenager that brought a Geiger counter to the building, and was subsequently "cleaned" up by employees equipped with dish washing gloves and a broken mop handle. "If you were in the Museum Collections Building (2C) between the year 2000 and June 18, 2018, you were 'exposed' to uranium by OSHA's definition," Stephenson wrote. "The radiation readings, at first blush, exceeds (sic) the Nuclear Regulatory Commission's safe limits. [...] Identifying who was exposed, and your exposure level, gets tricky and is our next important task." Stephenson said he had repeatedly asked National Park executives to inform the public, but never got a response. "According to Stephenson, the uranium specimens had been in a basement at park headquarters for decades and were moved to the museum building when it opened, around 2000," reports AZCentral. "One of the buckets was so full that its lid would not close. Stephenson said the containers were stored next to a taxidermy exhibit, where children on tours sometimes stopped for presentations, sitting next to uranium for 30 minutes or more. By his calculation, those children could have received radiation dosages in excess of federal safety standards within three seconds, and adults could have suffered dangerous exposure in less than a half-minute."
