《Destiny of the radioactive isotope》

What's called the 壊変系列 means the destiny of the radioactive isotope.Uranium buried in the ground repeats the change without any break.😃

Therefore,there isn't only uranium,but all other chemical elements made up of the chain 系列 in a vein 鉱脈 of the uranium.☝

As a consequence,the energy based on the collapse continue to be released.The energy keeps the earth warm.🌏

The uranium becomes radium or radon in the middle of the change.Some of them dissloves in the water.As a result,the water changes into hot spring,and we are pleased with it.♨

On the other hand,the chemical elements sometimes become poisonous gas.The gas appears in a basement.Then we hate it terribly.⚠

【Plutonium】

There used to be news in which plutonium was detected in a polluted area because of the nuclear power plant disaster in Fukushima prefecture.😥

The plutonium is produced as formed one of atomic fission with the uranium fuel.👷
