【How should we do with regard to the artificial atomic fusion?】

《A hydrogen bomb.》

The U.S.A. succeeded in developing the hydrogen bomb for the first time in the world in 1952.🇺�

The hydrogen and three-layered hydrogen of gas of have so little density that the atomic fusion doesn't happen,though I can't understand the reason why being little density prevented the atomic fusion from occurring😳

The American hydrogen bomb had so many attachments that its gross weight became no less than some 60tons.One of the attachments keeps the hydrogen cool and other one liquefies the hydrogen.😃

Even if,it was just the bomb,too heavy to carry with a plane then,but it was in the middle of the cold war between the western and eastern countries,so the Soviet Union succeeded in changing the bomb little in the next year.😒

《Being exposed to radiation》

A serious accident in which a fishing boat named 第五福竜丸 was exposed to radiation happened in 1954.😨
