This article is about Aktinum. Plutonium that enters the human body through food, blood (for example, wounds, etc.) or air is often accumulated in the lungs, liver and bones.So only 10%of other human institutions are accumulated.Plutonium remains in the human body for more than 10 years.The reason for the long accumulation time of plutonium in the body is unknown, but it is believed that the accumulation time is long due to the very weak availability of the plutonium.Some isotopes of plutonium emit ionized α-lines, which damage the surrounding cells.According to the speculation, the average fatal amount of plutonium is (LD50) and the drug containing the plutonium is injected into the vein, and after 30 days, it is estimated that it is 0.32mg per kg of the human body.It is estimated to be almost 22mg.(However, when the respiratory tract is exposed to plutonium, it is almost four times more powerful.) Another guess is that the plutonium is 50 times weaker than the radium, and then the accumulation allowed in the body is 5 µg or 0.3 µci.This amount is hardly visible under a microscope.After experimenting with the animal, the maximum allowable number of plutonium has been changed to 0.65 µg or 0.04 µci.In addition, animal testing was found that the most dangerous exposure method of plutonium was the respiratory exposure, with about 5-25%plutonium remaining in the respiratory tract.The amount of plutonium compounds is determined by the size and availability of the particles.Plutonium is gathered in the lungs or lymphatic systems or absorbed by blood and moved to the liver and bones.There are not many paths that are absorbed through food.In this case, only 0.05%soluble plutonium and 0.01%insoluble plutonium are absorbed by the blood and the whole is excreted.If plutonium is exposed through the damaged skin, almost 100%of the plutonium remains.
What is the fatal amount of plutonium per kilogram of human body?
