total doses from the chernobyl accident ranged from 10 to 50 msv over 20 years for the inhabitants of the affected areas with most of the dose received in the first years after the disaster and over 100 msv for liquidators there were 28 deaths from acute radiation syndrome

radiation is partly absorbed by the sarcophagus and also falls off with the square of the distance so even 500 metres outside the reactor the typical levels are almost 1000 times lower and that s as close as we d get though we would briefly experience higher doses elsewhere in the exclusion zone

radiation exposure levels compared as radiation exposure around the fukushima nuclear power plant reach levels of 400msv per hour although they ve since gone down we thought it was time to put the figures into perspective

radiation exposure levels compared click image for graphic as radiation exposure around the fukushima nuclear power plant reach levels of 400msv per hour although they ve since gone down we thought it was time to put the figures into perspective radiation is all around us all the time

the 1000 most exposed residents receive an average external effective radiation dose of 6 msv per year 0 6 rem yr six times the icrp recommended limit for exposure to the public from artificial sources
https://en.wikipedia.org/wiki/Background_radiation
this is four times the worldwide average artificial radiation exposure which in 2008 amounted to about 0 6 msv per year in some rich countries like the us and japan artificial exposure is on average greater than the natural exposure due to greater access to medical imaging
https://en.wikipedia.org/wiki/Background_radiation
The worldwide average natural dose to humans is about 2.4 millisievert (mSv) per year. This is four times the worldwide average artificial radiation exposure, which in 2008 amounted to about 0.6 mSv per year.
https://en.wikipedia.org/wiki/Background_radiation
to put this into context the average exposure from all radiation sources for a member of the public is around 0 26 usv hr one quarter of one millionth of a sievert the average dose received by nuclear workers is in the 3 25 usv hr range now let s look at chernobyl radiation levels in the control room immediately after the explosion reached around 300 sv hr providing a lethal dose in 1 2 minutes almost 22 years later levels inside the reactor hall today are approximately 34 sv hr a lethal dose in 10 20 minutes

there are a whole bunch of different ways you can measure radiation levels the most useful for our purposes is to measure the radiation dose ie the effect of the radiation on human tissue this used to be done in rems and is now done in sieverts 1 sievert 100 rem

record radiation levels were found in a house where the effective dose due to ambient radiation fields was 131 msv a 13 1 rem yr and the internal committed dose from radon was 72 msv a 7 2 rem yr this unique case is over 80 times higher than the world average natural human exposure to radiation

how many times the normal radiation
The normal radiation is about six times. The six times radiation is normal.
