【What kind of unit are what we call mSvﾐﾘｼｰﾍﾞﾙﾄ and microSvﾏｲｸﾛｼｰﾍﾞﾙﾄ?How much are they danger?😨】

Lots of people seems to be anxious about the phrase that total radiation exceeds criterion and some bombed victims because of the last nuclear power plant accident. I'm sure we need to make sure mSv and microSv which we often hear in the news is what kind of unit before we take action in a hurry.😃

Radiation are bathed　over we　human being whenever we live.Human bodies are　always exposed to the radiation. Its average of the world is about 2.4mSv,which is one thousandth×2.4 of 1 Sv, a year.😃

Lethal amount of　radiation　which causes death of bombed victim who was exposed　to radiation for short period is 5％ lethal amount of radiation which causes death,2Sv, it means 2,000mSv.💀

The number of 5％ means the　leathal amount　of radiation which causes death of one of 20people who are exposed to the radiation.💀

To be continued. By😁
