【Kinds of the radioactive material】

② Plutonium

The plutonium is being used in an ordinary reactor as fuel,what is called the fuel of MOX,being mixed up with uranium with the MOX project プルサーマル計画 at present.😃

I'll express the fuel of MOX and the MOX project later.😃

③ Iodine

Iodine ヨウ素 is included in a seaweed,but it's the iodine127,and has no radioactivity.It's iodine131 which is dangerous.😨

When undergoing the nuclear fission 核分裂,the iodine131 is created.I'll express the number of 127 and 131 means in the next chapter.Please regard them as atomic relative weight for the time being.😃

④ Cesium

While natural cesium133 isn't dangerous at all,other cesium137 which is created with the nuclear fission is very perilous,for it has the radioactivity.⚠

The cesium137 is mass-produced by nuclear fission with the iodine,so when making sure whether or not the radioactive material is released,we adopt the iodine,though I'm wondering how the iodine is used for it then.😚
