This is radioactive material, usually appearing in loads of scrap metal or trash destined for recycling or disposal, which cannot be readily identified nor can ownership be easily determined. The Conference of Radiation Control Program Directors (CRCPD) has entered into an agreement with the US Department of Transportation (USDOT) to exempt shipments of scrap containing such material from DOT regulations, subject to certain conditions, in order to allow its expeditious return to its point of origin. The exemption text and exemption forms may be viewed through the following links.
