【What is the radiation?】

The radiation is a thing which the radioactive material gives off.It's very perilous and invisible.Even if the radiation passes through our body,we can't recognize it at all then,but we'll end up having a bitter experience later.😨

《Image of the radiation》

A word of radioactivity which ordinary people imagine is equal to the radiation.If the radiation passes through our body,it'll be harmful to our health,our lives are sometimes threatened.⚠

However,we can't see it with our own eyes.Without using a measurement instrument,we can't acknowledge whether there is the radiation or not around us.⚠

《Kinds of the radiation》

Alpha ray is the biggest and heaviest among the radiation,but it's a atomic nucleus 原子核 of helium which flies in the air at high speed so much that it's invisible.Even if we can't watch it with even an electron microscope.😨

However,it's heavy and large,besides it has an electric charge 電荷,so we can protect against it easily.😃
