What I meant is that there are min. levels people can tolerate for a specific amount of time before it causes damage to your body. Maximum levels are when you begin to experience illness or long term effects.
Perhaps a misunderstanding, I am not having a good day.
I think they idea of a min and max is misleading. As you mentioned, it is time dependent. It should be thought of as a sloping line on a graph over time.
I know people want to simplify to gain or give understanding. But radiation is a cumulative effect, very time dependent.
Understanding that helps people realize how the workers can survive in “unacceptable” high levels to supply water to the pools and the like.
Cheers
There are studies that have shown that above average exposure to radiation has been beneficial. I don’t claim to be an expert nor have I examined the validity of these studies.
This is not the definitive source, but mentions some of the studies. http://www.anncoulter.com/cgi-local/printer_friendly.cgi?article=414
