Where did the cylinder containing a dangerous radioactive substance go, which disappeared from a Thai power plant? Staff at the coal-fired power plant in Prachinburi province, east of Bangkok, noticed the 30 centimeters long and 13 centimeters wide steel tube missing during a routine check. , last Friday. On Tuesday, authorities warned Tuesday of serious health risks from direct exposure.
A search over the weekend failed to locate the 25kg tube containing highly radioactive cesium-137, said Kittiphan Chitpentham, a member of the national energy utility, which owns the plant. The company assumes that the tube fell from a wall support, about 18 meters high, a few days earlier.
Do not open the cylinder
Radiation tests carried out at the factory show that he has since been removed from the premises. “We are asking people in the area to help us find him,” said Narong Nakornjinda, the governor of Prachinburi province. “The radioactive substance is contained in a closed and protected environment, but if someone opens the cylinder and exposes themselves to this substance, it can cause rashes and burns,” he warned.
The missing cylinder is part of a device used to measure the pressure of the plant’s steam column. Authorities have not specified how much cesium-137 it contains. The authorities are trying to identify the person who took the cylinder thanks to video surveillance images, added the government agency in charge of nuclear research, also advising against opening the cylinder.
A similar incident in Australia
“If someone breaks the cylinder, they directly put themselves at high risk of cancer and serious illness. It is therefore advisable not to break it,” said Permsuk Sutchaphiwat, secretary of the government agency. The disappearance of this cylinder comes a few weeks after a similar incident in Australia, where authorities found a small radioactive capsule that fell from a truck in mid-January after two weeks of research.
