And it was only detected by accident! > On January 16, 1984, a radiation detector at Los Alamos National Laboratory in the U.S. state of New Mexico detected the presence of radioactivity in the vicinity. The detector went off because a truck carrying rebar produced by Achisa had taken an accidental detour and passed through the entrance and exit gate of the laboratory's LAMPF technical area.[6] Local authorities realized that the rebar triggered the alert and notified Mexico's National Commission on Nuclear Safety and Safeguards [es] (CNSNS) on January 18. CNSNS confirmed a wide dispersion of radioactive material had occurred and ordered Achisa to suspend the distribution of manufactured rebar until it was verified that it was not contaminated. Mexican authorities also proceeded to close the junkyard.[4]
