Grand Canyon tourists exposed for years to radiation in museum building

Technicians did not have protective clothing, so they purchased dish-washing and gardening gloves from a general store. They then used a broken mop handle to lift the contaminated buckets into a truck.

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.
