Re: LNT and resources [Was: Scientific responsibility]
Many thanx for your response. I've had the same experience. When I was with
a DOE contractor, and reviewed research projects, the researchers sometimes
claimed that my safety requirements would kill the project. (However, they
didn't call me a "criminal.") Never happened!
The opinions expressed are strictly mine.
It's not about dose, it's about trust.
Curie forever.
