Health examinations of all 93 workers in a construction site in Nanjing, Jiangsu province, where lost radioactive iridium-192 was retrieved, showed normal results on Sunday, local officials said.

"The environmental bureau received the information about the missing iridium at 2 am on Friday and immediately formed a response team, together with police," said Zhang Shida, director of the Nanjing environmental bureau's nuclear and radiation management department.

The iridium-192 went missing on Wednesday morning during a monitoring operation by Tianjin Hongdi Engineering Inspection Development Co Ltd, at a construction site near Puliu north road in Luhe district.
