Why can't nuclear radiation survivors wash their hair immediately?

Nuclear energy is a very important energy source in our life, may not be very common, but it occupies a very important position. Our country has mastered this technology, and thus gained a huge military promotion, from a large aspect to enhance our national defense force. Nuclear radiation, however, is very bad for the human body. When humans are infected with nuclear radiation, they basically lose 50% of their chances of survival.

? In WWII, Japan was greatly weakened by the 2 missiles dropped by the US, and thus was unable to win WWII. People who experienced such an accident essentially lost their lives, and the occasional person who survived from a distance was disabled for life. In fact, in 1986, Japan's nuclear radiation incident can be seen, nuclear radiation, but the leak will have what kind of serious consequences, until today, people mention the then nuclear radiation leakage incident, or will be palpitating.

? Nuclear radiation survivors are not allowed to wash their hair immediately, there is a certain reason for this. Because the hair on the surface of our skull is the largest area that can be exposed to radiation, in the absence of washing hair, hair radioactive particles are open, at this time, the radioactive particles will adhere to the hair, but once you wash your hair, the radioactive particles will be closed with the hair particles into the scalp, and it is easy to cause secondary damage to the body.

? The radioactive fallout will slowly diminish with the passage of time, about 7,8 hours after the radiation has passed, its damage will be minimized. At this time, it is possible to wash your hair if you want to. The length of time to wash your hair is a matter of personal habits, so it is safest for survivors of nuclear radiation to tolerate the radiation for 7 or 8 hours to ensure that the damage from the radiation is minimized before washing their hair.
