This value DOESN'T influence our health so much. For example, if you go to New York from Tokyo by airplane, you may be exposed to radiation 190 micro Sv/h. Or, when you have a X-rays medical examination, you are exposed to radiation 600 micro Sv once.
But, it is fact that you are exposed to more radiation than usual. You should be careful and had better stay inside.
