But of course we know that extensive data confirm that LDR does enhance health in mammals! :-)
And exposures of hundreds of thousands of fish showed dramatic effects in lifespan and health.

Good point. I remember old experiments on the sensitivity of fish eggs in
the Ottawa river around AECL's CRNL labs. Radiation was shown to increase
the "viability" of the eggs but we said that this could not be applied to
