Charles Ader/ Maria Lopez-Otin
Subject:
BRC POLICY Since " turn around 'is fair play", and we have had a chance to comment on your BRC " straw man", below you will find ours.
(I understand that Charlie has discussed the approach conceptually-with both the Carr and the Curtiss office).
In a-nutshell, our philosophy is that 10 mrem with a 1000 man-rem collective dose is the BRC number.
However, since we have no practical experience (nor crystal ball) that would tell us how many practices an individual can be exposed to, for now.we will allow unrestricted distribution _ and use of any practice or product at 1 mrem or below.
Those practices / products at 10 mrem would be subject _to the collective dose analysis.
POSSIBLE APPROACH FOR BRC POLICY
- Between 100 mrem and BRC Allow practices if ALARA and justified.
Justification to be made based on health risks.
BRC Level-Establish a BRC level at 10 mrem with a collective dose of 1000 man-rem as a floor for ALARA.
Because of concern that multiple practices may result in levels approaching 100 mrem, for wide spread
- use, i.e.,
consumer products use 1 mrem, until further experience is gained.
Truncation Use thelNCRP recommendation for 1 mrem.
