>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.
>The Nuclear Regulatory Commission measures radiation contamination in millisieverts per hour or per year. According to Stephenson, close exposures to the uranium buckets could have exposed adults to 400 times the health limit — and children to 4,000 times what is considered safe.
