Radiation units are a bit weird. Sieverts are normalized to biological damage, because units of energy are insufficient to differentiate between 1 J of sunlight

Radiation 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).
