The accident occurred on June 7, 2009. Because the goods fell at the head of the lead well where the radioactive box was stored, the radioactive box containing the radioactive source cobalt-60 could not return to the lead well normally. As a result, the radioactive source remained in working condition. Because of fear and panic, many people fled their hometowns, and government workers took "shelter" to nearby counties and cities. The local police have arrested 5 people who spread rumors about the incident, 1 of whom was detained criminally, and 4 were punished by public security.
