"- studies of present nuclear workers have shown no increases in cancers."
Indeed! Cameron showed DECREASE, recently published again by Sponsler.
Logic suggests, NOT that , "ALARA does work," but hormesis benefit from background radiation increased to mountain state levels, at least.
Jacobus' logic perpetuates error, huge tax costs to actually deprive of "An Essential Trace Energy" (Cameron), - and regulators' jobs.
ALARA kills. www.aps.org/units/fps/oct01/a5oct01.html
I believe that the ALARA concept is based on
minimizing unknown future risks. The solid cancers
that was seen after such events as the radium dial
painters and the bombings of Japan occurred years
after the exposures. With ALARA, epidemiological
studies of present nuclear workers have shown no
increases in cancers. Maybe it really does work.
