Radionuclides can produce strong radiation to the surrounding environment and cause nuclear pollution. Radioactive fallout can also enter the human body through the food chain, which will have harmful effects when it reaches a certain dose in the body. People will have dizziness, headache, loss of appetite and other symptoms, which will lead to leukopenia and thrombocytopenia. If excessive radioactive substances act on the human body for a long time, it can make people suffer from tumors, leukemia and genetic diseases; It is found that gene mutation can occur under special circumstances.
Captured? High radiation fish? A thick-headed flounder about 28 cm long was found to contain 254,000 Bekkerel of radioactive cesium. Japanese Food Safety Law stipulates that the content of radioactive cesium in general food should not exceed 0/00 becquerel per kilogram. This shows that the radiation content of 28 cm thick-headed flounder has exceeded the standard by 2540 times.
People eat fish after nuclear radiation, and a certain amount of radioactive substances are released into the human body. The biochemical toxicity of radioactive substances can cause harm to human body through its radiation. This effect is called internal irradiation; External ionizing radiation can also cause damage to human body, which is called external irradiation. Radiation damage is the general name of various biological effects caused by various ionizing radiation acting on human body.
This is due to various ionizing radiation (such as x or? Ray. Ray. Radiation and neutron beams, etc. ) causing ionization and excitation should transfer energy to the body and cause pathological changes of various tissues and organs. Radionuclides can produce strong radiation to the surrounding environment and cause nuclear pollution. Radioactive fallout can also enter the human body through the food chain, which will have harmful effects when it reaches a certain dose in the body. People will have dizziness, headache, loss of appetite and other symptoms, which will lead to leukopenia and thrombocytopenia.
