At the NCRP meeting an NRC presentative indicated that they were not going to eliminate there ALARA requirements in their regulations. So it goes.
I thought that it was interesting when the monitor at one question session told Ted Rockwell that if he did not a valid question of the panel to sit down. Sad but true.
Sorry you could not make it Dr. Long.

You have strong help from Ted Rockwell in,
Creating the New World: Stories and Images from the Dawn of the Atomic Age.
Therein, Ted relates the value of submariner perfectionism in selling and
making the first nuclear power plants safely.
However, now that instrumentation and evidence that up to 20 rem/year actually
promotes longevity and reduces cancer, isn't it time to draw that line?
Prompt energy increase depends on it.
All would agree that great pains must be taken to assure there is no repeat of
