Age based dose limit

[Lester Slaback <Lester.Slaback@NIST.GOV>]

Another, not so minor point to remember is the age based limit is based on 
a real, whole body exposure (and a LNT model which we will ignore at this 
point).

Remember that the NRC dose record reflects a dose purposefully biased on 
the high side since, among other things, it reflects the highest exposed 
point of the body. Hence in many cases does reflect a similar risk.  So 
limiting work based on this record relative to the age limit would really 
seem to be excessively conservative.
