Re: Contaminated Scaffold Knuckles - Turkey Point



Interesting! Several years ago, I did a report for the DOE that included a

recommendation

to the effect that any material <1.0 nci/g could be considered de minimis,

i.e. essentially non-radioactive, regardless of the radionuclide(s)

involved.

I  tried to conceive a scenario (assuming Pu-239) where implementation of

this limit could result in significantly adverse health consequences, but

failed.  Can anyone suggest such a scenario?
