When did Co 60 escape in Qixian County?

The accident happened on June 7, 2009. Because the goods landed at the lead well where the radioactive box was stored, the radioactive box containing radioactive source cobalt 60 could not return to the lead well normally, and as a result, the radioactive source was always in working condition. Because of fear and panic, many people fled their hometowns, and government workers took refuge in nearby counties and cities. The local police have arrested five people who spread rumors about the incident, of whom 1 was criminally detained and four were punished by public security.
