Could someone clarify how radiation dosing and dose rates are measured?
The article says background radiation levels peaked at .15 mSv in 1963. Looking at the wikipedia page on Seiverts, I am trying to compare this to other radiation examples, but not sure how to draw a comparison.
Would a human standing outside be receiving .15 mSv per hour? year? total?
- tedsanders 13y agoRadiation units are a bit weird. Sieverts are normalized to biological damage, because units of energy are insufficient to differentiate between 1 J of sunlight and 1 J of x-rays. I think the 0.15 mSv the article mentions is per year. The next sentence says per year explicitly.
- bradleyjg 13y agoIt's an odd reference in the context of reduced need for special pre-war II non-irradiated steel. From the article if looks like the most important factor for that would be atmospheric concentration of Cobalt-60 (in ppm or ppb).
