【Is the criticality a terrible phenomenon?】


《Chain reaction》

Therefore,we must not make the amount of criticality exceed.⚠


An atomic nucleus of the matter which voluntarily releases neutrons and causes chain reaction branched off always continues to give off the neutrons.☝

If one of the neutrons bumps against the other atomic nucleus,and make it undergo fission 核分裂,other neutrons will be generated.Then the neutrons collides with another atomic nucleus…😨


If worst comes to worst 最悪の場合,it becomes an atomic bomb,and may cause a nuclear explosion.🔥


Let's suppose there was a lump of uranium.It has its own atoms of which numbers are astronomical ones,and keeps on emitting the neutrons with the fixed probability,but all the generated neutrons don't collide with the atomic nucleus.😃


The relation between the atom and the atomic nucleus resembles the one between a tremendous domed baseball stadium and a pachinko ball.Then the neutrons are equivalent to grains of sand.😃
