Strict regulations govern the transportation and handling of radioactive material.
Irradiation facilities are constructed to withstand earthquakes and other natural disasters without endangering the community or workers. Radioactive material is transported in canisters tested to withstand collisions, fires, and pressure. The 60Co used by US commercial facilities is specifically produced for use in irradiation of medical supplies and other materials. It is not a waste product of any other activity, and it cannot be used to make nuclear weapons. Disposal of 60Co is carefully arranged by the producer.
