【What is the radiation?】

《Kinds of the radiation》

By the way,I'm not sure difference between particles and electromagnetic wave is.I'm sorry for it💦

Ray of neutron 中性子 is high speed flow of the neutron.The neutron is neutral electrically,and doesn't have an electric charge as its name indicates.😃

It's said the ray of the neutron goes through almost all of things,so it's hard to protect them from passing through.😨

Therefore,the ray of the neutron seems to be most tiresome among the radiations.It's said we need lead of which thickness is more than 1meter in order to prevent the radiation.☝

Ray of proton 陽子 is high speed flow of proton.It's useful radiation which doctors make use of in a medical treatment of cancer.💉

Other radiations are 重粒子線 such as carbon or neon.They are high speed flow of atomic nucleus 原子核.They are also being paid attention for the medical treatment of the cancer recently.💉
