Reply #51: So would I. At 10E7 x the normal safe exposure window is about 2/5 second. [View All]

And about 4 seconds for permissible emergency exposure levels. (10 seconds for an extreme emergency.)

It's also probably about the real exposure level of the those Chernobly workers standing knee deep in pulverised reactor core, whilst shovelling it back into the building.

For 10,000 x normal (which does match figures announced earlier), the permissible "emergency" window is roughly an hour (or 2.5 hrs) which is just barely enough to cause a very small number of additional cancers in a fairly large population.
