Nuclear radiation cannot spread to Vietnam

In some incidents of a nuclear power plant, radioactive substances such as iodine (iodine 131 and iodine 129) and cesium (Cesium 137), if left unchecked in the furnace or the kiln will be released to the lips. school

The life of iodine 131 is very short (8.02 days), while iodine 129 (nearly 16 million years) when it spreads into the environment will spread to vegetables, land, animals . Cesium 137 with a life of 30 years , is also one of the radioactive contamination released into the environment in some incidents of nuclear power plants. The dispersal of cesium in an environment that is not wide, as far as iodine, only floats a few centimeters (cm) on the ground and clings to plants and flowers but cesium can be wired to the food chain of the species. people and animals. If absorbed, they will focus on the muscles and after 100 days will be removed from the body.

According to updated information through reports from Japanese nuclear safety agencies, the level of radiation spread to the environment is about 1,020 microSievert / hour, exceeding the normal level very high (under normal conditions, radiation levels). is is 0.05-0.1 microSievert / hour). The radius of the dispersal of the above radioactive substances during the incident will be related to the meteorological details (direction, height, wind speed) during the time of the incident. Can spread within a radius of 3km to 100 or over 1,000 km depending on meteorological characteristics as stated.

According to calculations by calculation of the French nuclear safety agency, the direction of radioactive dispersion of the 1, 2 and 3 nuclear reactors of the Fukushima 1 plant will go towards the Pacific, but not spreading about Vietnamese territory. However, when they have arrived in Vietnamese territory, the authorities, such as the Nuclear Radiation Safety Department, the relevant departments and agencies . will organize and coordinate methods to ensure health and The safety of the people, depending on the level of radiation, such as: giving to the people radioactive iodine medicine, advising the people to stay indoors or evacuate the population of the area that has been contaminated with radiation to a safe area .
