【What is the radioactive material 放射性物質？】

What is the radioactive material? It's a material which emits radiation.It's just the material,so it has not only volume 体積 but mass.😃

《The radioactive material》

The radioactive material is substance which gives off the radiation,so we are liable to think it‘s dangerous and unidentified thing like radiation.😚

However,it's just the material,it has volume and mass,but somebody may object like next.“It's natural. Does the material which has neither volume nor mass in the world?”

Light is equivalent to the thing. Needless to say, the light isn't the material, therefore the radioactive material which isn't the light is an ordinary thing.😃

《Size of the radioactive material》

The radioactive material is the substance,so its sizes are varied like iron.While the iron changes into a tanker of which weight is 0.1 million tons,it becomes a pachinko ball.🚢

The iron turns into an atom in which is Hemoglobin of red blood corpuscle 赤血球.It also changes into ion.🙋
