【How dangerous is the radiation?】

《Serious damage》

To make matters worse,when the amount of being radiated reaches to 10.000 mSv,it means 10 Sv,we'll fall into 意識障害,and when reaching to 50 Sv,we'll be dead within 2 days.💀

【How much is the radiation in the natural world?】

The radiation is very harmful to a living body,but it's full of in the natural world.It is said that it's 2.4 mSv that a person receives the radiation a year.😥

However,the living bodies have envolved,enduring the radiation.In short,the living body has a tolerance to the radiation on the earth a lot.😃

《Being bombed from the universe》

Cosmic rays pour down from the universe.They are mainly very harmful such as gamma rays or proton 陽子 rays,but they are being absorbed in the ozone layer which is at the stratosphere 成層圏 of high altitude.🌌

It's said without the shelter,neither living bodies could survive nor would be born on the earth.💧
