AW: [ RadSafe ] Cameron's refutation of "Alara Does Work"

Pollycove and others (with far more "standing"than myself)
have reviewed (for DDP presentations) studies"shedding doubt " on Cameron's assertions by Boice and others. They sided strongly with Cameron.
"'Healthy worker effect" was the only serious contention. We all believe the p was far too small to invalidate conclusion of hormesis. Definite benfit came from the 0.5 rem added "essential trace element" of Cameron: ionizing radiation.
Also, benefit to rats and cells in studies reviewed by Pollycove and his neat explanation of biologic defense stimulation ( mind-boggling 9 orders of magnitude
more oxygen-caused free radicals than the radiation - stimulated defenses). This
also confirmed hormesis.
The one question (raised by a radsafer) which made me double check the p effectors was:
"Could applicants with questionable health have been steered away from exposure by admitting physicians?" I believe this is possible, but not with sufficient power.
