as we all know, the super radiation food in our daily life will bring great harm to human body, so we must keep away from it. Do you know the harm of the radiation fish? Japan has found the super radiation fish recently, let's take a look at it with Sihai net. The 7th anniversary of Japan's 311 earthquake and Fukushima nuclear disaster is approaching. Tokyo Electric Power Company conducted an investigation in the town of dashungcho, where the Fukushima No.1 nuclear power plant is located, and detected radioactive cesium in fish about 4 kilometers offshore, which is more than twice the national standard of Japan. TEPCO announced its findings on Saturday.
According to dongwang.com, Dongdian will regularly spot check the fish in the sea area and monitor their radiation content. The results of the spot check on February 2 showed that 358 Becquerels of cesium were contained in every 1kg of small fin redfish, more than 100 Becquerels of the Japanese national standard. If you eat 200 grams, it's equal to 1 / 50 of the chest X-ray exposure, about 1 milliSievert.
It is reported that the test fishing is carried out in the 10 km sea area around the Fukushima Daiichi nuclear power plant.
What happens when people eat radiation fish?
After people eat the fish after nuclear radiation, a certain amount of radioactive substances enter the human body. The biochemical toxicity of radioactive substances can cause human body damage by its radiation effect. This kind of effect is called internal irradiation; external ionizing radiation can also cause damage to human body, which is called external irradiation.
Radiation damage is a general term for various biological effects caused by various kinds of ionizing radiation acting on human body. This is due to the ionization and excitation of various ionizing radiation (such as X or & gamma; ray, beta; ray, alpha; ray, neutron beam, etc.), which transfers energy to the body and causes pathological changes of various tissues and organs. Radionuclides can produce strong radiation to the surrounding area and form nuclear pollution.
Radioactive fallout can also enter the human body through the food chain, and will have harmful effects when the body reaches a certain dose. People will be dizzy, headache, loss of appetite and other symptoms, the development of white blood cells and thrombocytopenia and other symptoms. If the excessive dose of radioactive material acts on the human body for a long time, it can make people suffer from tumor, leukemia and genetic disorders; research has found that gene mutation can occur under special circumstances.
