【Do radiations penetrate?】Ⅱ

As for its title of last renar, I made a mistake. I should have expressed like above one. It's shameful of me to make a rudimentary 初歩的 mistake😳

I'm going to continue to express my remark. Unless we touch the radioactive materials which generates alpha rays directly,or take in our body,we don't have to be worried about it excessively.😃

We can also shut out beta rays with a thin metalic plate such as aluminium.Even if there is nothing between us and the beta rays,they stop with a few meters in the air. 😃

As long as we take refuge indoors,we won't be under the beta rays.😃

The problem is ganma rays and neutron ones.Without a thick lead 鉛,or iron plate or thick wall,we can't shut out the gunma rays completely.😠

As for the neutron rays,we can't protect enough with even the lead metalic plate which can protect us from ganma ones.

It is said water and paraffin,it means a kind of wax,are suitable to shut out the neutron rays.😔
