from radioactive materials “Cesium-137” (Cesium-137, Cs-137) of the NOS 5a power plant in Si Maha Phot District, Prachin Buri Province was lost. There is lead protection in the inner layer. and encased in a round steel tube Its diameter is about 6 inches, its length is about 8-9 inches, it weighs 25 kilograms, which it has not yet been found. causing concern that There may be people who don’t know it’s a hazardous material. and have exposure to affect health
On March 20, 2023, Mr. Permsuk Sajjapiwat, Secretary-General of the Office of Atoms for Peace, and Mr. Ron Ron Nakornchinda, Governor of Prachin Buri Province jointly discussed ways to search for such radioactive materials and press releases about it. at the learning center Prachinburi City Hall, 4th floor
On March 20, 2023, Mr. Permsuk Sajjapiwat, secretary-general of the Office of Atoms for Peace, said that at this time, we found that the object containing caesium-137 had disappeared and that the clue was found at the smelter. having melted I must learn that the original item was lost by humans. That we have to keep track of how it disappeared. This event is an incident (Incident) that has not affected human life. It’s not a nuclear accident like Chernobyl or Fukushima. This incident started on March 10, 2023 from the 1961 law used during the Cobalt 60 incident. 2016 that has received international recognition
The secretary-general of the Office of Atoms for Peace continued that the new statute said that if he knew that the radioactive device was lost, he had to report it immediately. But when not immediately notified, then this incident happened. We can therefore be tracked by atomic tools for peace. After notifying the team to inspect the factory the next day But now the factory still doesn’t know why it’s gone. This factory has been holding this material since 1995. It has always been well taken care of and the installation point is very high. The security system is very good. high quality perimeter fence excellent management Therefore, it has been allowed to use this material all along. to be radioactive materials in equipment We work well with different sectors.
Scientist of the Office of Atoms for Peace Caesium was found in red dust. or iron dust that comes from melting iron into boiling water and there will be soot floating up when cesium at low boiling point thus evaporating with soot When the molten iron has been rolled out into bars into strips Therefore not found in the iron that has been rolled out But in the furnace, there is still red dust from smelting steel from a closed furnace. will be recycled because these dust have a price And there is cesium that has become a salt powder contaminated with it. which is not everywhere According to the inspection of red dust sent to Rayong Province, there was no cesium found in the recycling plant.
In the factory we went to block the area in the area. Kabin Buri District to send a team for a detailed examination using high-performance inspection tools Both outside and inside the factory makes us confident that There was definitely no such device in the factory. and found cesium at the smelter Today we sent a public health team to examine the body for substances. whether the residue in the employee’s body or not
There were 24 bags of red dust contaminated with cesium, 24 tons, of which 1 bag was taken to fill the land behind the smelter. It was dug back and filled with all the bags. and enclosed the said land From now on the investigation of the disappearance We will try to find out whether Where did the person take the equipment? But at this time we cannot 100% confirm that the cesium found was from a lost factory.
