Workers have found radioactive cesium-137 in one of three metal melting furnaces. The Office of Atoms for Peace has set up a task force to monitor and respond to the situation. They measured low radiation contamination at 0.07-0.10 microSv/hr in the contaminated furnace, while furnaces one and two reported no contamination, neither did the iron water transfer parts. There is also contamination in the dust extraction and dust filtration systems, and a certain amount of dust in the caesium-137 metal dust filter system from smelting metal on March 18-19, 2023. After the contaminated dust cools, they will package it into large bags and store it in a previously contaminated 24-tonne red dust shed. Office of Atoms for Peace staff measured the radiation dose around the factory at a radius of three km, as well as in the surrounding communities, to build public confidence and explain the measurement methods and radiation levels. The Office of Atoms for Peace collected urine samples from factory employees, to test in their laboratory for gamma rays. They seek assistance from the Department of Science, Royal Thai Army, Department of Naval Science, and Department of Science, Air Force to coordinate with radiation experts, who continuously perform radiation measuring instruments to confirm no further contamination.
Cesium-137 found again in a furnace. Prepare to ask the Department of Science for the help of the military.
At 4:00 p.m. on March 21, reporters reported that Mr. Kittkawin Aramrun, Head of Nuclear and Radiation Emergency Operations Center, Office of Atoms for Peace As an Assistant Spokesperson of the Office of Atoms for Peace reporting on the operational situation case of contamination cesium-137 In the smelting factory, a coordination center was established to monitor the situation. and the Office of Atoms for Peace has set up a task force to monitor and respond to cesium-137 cases. at the factory scene And check the radiation dose measurement in the factory. Total Vulcanization System
Contamination with radioactive cesium-137 was found. In one of the three metal melting furnaces The results of measurements of radiation contamination were low (0.07-0.10 microSv/hr), while furnace No. 1, 2 found no contamination. and no contamination was found in the iron water transfer device parts. Contamination was also found in the dust extraction and dust filtration system. And there is a certain amount of dust in the caesium-137 metal dust filter system. From the smelting of metal on March 18-19, 2023 Which is now waiting for the contaminated dust to cool down first and will be prepared to pack into large bags It will then be stored in a previously contaminated 24 tonne red dust shed.
After that, Office of Atoms for Peace staff measured the radiation dose around the area. At the soil around the factory, the amount of radiation measured is equivalent to the amount of radiation in nature. Investigation of the ambient radiation dose in the environment It was carried out by using a dosimeter installed in a car to measure the amount of radiation around the factory where the accident happened. The results showed that the measured radiation dose was equivalent to the natural radiation dose. (0.03-0.05 µS/h) 
Measure the radiation dose around the factory in a radius of 3 km. We work with the government that goes into the community in 4 large points: Khok Krathon Village, Moo 10, Lat Takhian Subdistrict, Song Village, Moo 2, Hat Nang Kaeo Ban Subdistrict. Hat Sung, Moo 2, Hat Nang Kaeo Subdistrict and Hat Nang Kaew Subdistrict Administrative Organization to build the confidence of the public In terms of explaining measurements and radiation levels to people around the factory area Regarding the measurement method for assessing the value of cesium-137 received into the body We have collected urine samples from employees in the factory. Which will take the urine to be tested at the laboratory of the Office of Atoms for Peace. with a gamma ray meter
In nature, there is already radiation. Caused by the ground, outer space radiation, these rays we call natural radiation. Caesium-137 radiation We have to create only We have partners to coordinate radiation experts. Department of Science, Royal Thai Army Department of Naval Science Department of Science, Air Force which this agency has training all the time These units will have radiation measuring instruments. will be able to check and check again According to the antique shop or other factories to confirm that this lump has not been found we can ask for cooperation metal parts containing cesium-137 We will coordinate with the Ministry of Defense to be able to support in the area to help find another way as well.
In conclusion, the discovery of cesium-137 once again in a furnace highlights the importance of maintaining rigorous safety protocols in industries involving nuclear and radiation materials. The Office of Atoms for Peace has initiated measures to monitor and contain the contamination, with a task force set up to respond to the situation. Urine samples will also be collected for testing to assess the extent of the contamination among employees. It is crucial that the authorities work closely with radiation experts and other relevant agencies to ensure the safety of the environment and the public. Let us hope that this incident serves as a reminder for all industries dealing with nuclear and radiation materials to prioritize safety and preventive measures.
