But it turns out that at one point a bizarre sequence of events led to a rather odd nuclear disaster occurring there. So how did they have a widespread nuclear disaster? By January 16, 1984, one of the trucks that carried some of the radioactive steel through the United States got lost in New Mexico. It is believed that thousands of tons of radioactive steel rebar was transported to multiple Mexican states to be used in housing and buildings. More worrying is that there is no way to measure the actual damage to those exposed on the long run due to stray pellets or houses made with contaminated steel, etc.
