RE: Radon Levels

["Reynolds, Harold" <Harold.Reynolds@rfets.gov>]

I believe 4 pCi/L converts to about 1 WLM/year. Keep in mind that to get
from pCi/L gas to WL progeny, you have to make some pretty iffy assumptions
The number I remember using for this is about 14 rem/WLM, but I don't recall
the source.
