Detecting small amounts of radioactivity in the air in Vietnam

The Ministry of Science and Technology said a monitoring station in Vietnam has detected radioactive substances in the air, but fortunately the content is only small and does not affect human health.

" The monitoring station of the Institute of Nuclear Science and Technology of the Vietnam Atomic Energy Institute has detected radioactive isotopes of I-131 in the air, " the report said tonight.

"However, the content (this substance) is very small, does not affect human health ."

According to the report on environmental radioactivity data of the organization that banned the comprehensive nuclear test CTBTO, the image simulating the radioactive cloud shows that, in the Pacific Ocean, cloudiness is increasingly spreading southward compared to Japan. The village , where nuclear power plants are leaking radiation into the environment.

In Southeast Asia, on March 28 and 29, radioactive clouds still tend to advance to Indonesia and Malaysia.

The monitoring stations of CTBTO network are very sensitive and can detect radioactive nuclei with very low concentrations in the atmosphere. This concentration may not affect human health, the report stressed.

So far, the closest station in Vietnam has stations in the Philippines that have detected radioactive nuclei.

According to the simulation, radioactive clouds in today and tomorrow have not yet entered Vietnamese territory.It has a tendency to spread, seemingly approaching Vietnam in the southeast.

By the end of March 29, there may be a few small clouds lying close to the north near Hainan Island (China) and south of Ca Mau Cape and Phu Quoc Island of Vietnam, announced by the Data Center. Vietnam belongs to the CTBTO network.

In the coming days, whether this cloud will spread to Vietnam depends on the meteorological conditions of Southeast Asia. However, if the radioactive cloud reaches Vietnam, it is difficult to detect its influence on the radiation background in Vietnam.

In Japan, the overcoming of the nuclear incident at the Fukushima I factory is still complicated, including radioactive leakage through steam escaping from the reactor and burnt fuel tank; The phenomenon of contaminated water flooded in the floor of the reactor-containing building has not been overcome, so workers cannot approach to repair machinery and equipment.

In the meeting this afternoon with Deputy Minister of Science and Technology Le Dinh Tien, Japanese expert Satoru Toshimitsu, Chief Representative of the Japan Nuclear Power Industry Forum (JAIF), and Public Representative Japan International Nuclear Power Development Company (JNED) in Vietnam, said that the situation only worsened if the earthquake and tsunami continued in the factory location.

Otherwise, with the help of IAEA and other countries, Japan can control and minimize the consequences of nuclear incidents at Fukushima 1 Factory and can eliminate the possibility. the possibility of a nuclear explosion at the reactors is like the case of Chernobyl.
