Sentences with phrase «background radiation due»

Not exact matches

According to previous simulations, UV - B radiation at the end of the Permian may have increased from a background level of 10 kilojoules (just above current ambient levels) to as much as 100 kilojoules, due to large concentrations of ozone - damaging halogens spewed from volcanoes (SN: 1/15/11, p. 12).

The distributions of annual external doses estimated for each region overlap with each other, demonstrating that the personal external individual doses in locations where residence is currently allowed in Fukushima Prefecture and in Belarus are well within the range of estimated annual doses due to the background radiation level of other regions / countries.

The additional exposures received by most Japanese people in the first year and subsequent years due to the radioactive releases from the accident are less than the doses received from natural background radiation (which is about 2.1 mSv per year).

And remember, we are talking about an additional radiation exposure in the realm of 0.0002 mSv for those living near a nuclear power plant, versus a background level of 2 to 4 mSv (depending on where you live) due to everything from cosmic rays to ground - derived radon emission to eating bananas (this last one gives you more radiation than the NPP).
