"minimal risk"?

[Sandy Everage <severage@life.edu>]

I am hoping that someone can help our Institutional Review Board (Human
Subjects Committee) in deciding what constitutes more than "minimal
risk" from x-ray exposure.  Is there a maximum mrad amount that could be
considered "minimal risk", in which research proposals could go through
expedited review, or should all research involving radiation require
full-committee review?
Thanks for your help.
