Prachin Buri province raised its dangerous situation alert to Level 2 on Wednesday as the search continued into its second day for a missing bulky tube containing radioactive caesium-137, a highly hazardous isotope.
Level 2 means the provincial government is required to take charge of the operation being carried out to deal with this specific threat to public safety, said Narong Nakhonchinda, the provincial governor. Level 4 indicates the highest threat to safety.
