[ RadSafe ] Buildup factor for compounds

[Kai Kaletsch]

Hi John,

My question actually came about by looking at the peculiar results you get 
when using MicroShield. For example MicroShield's calculated value for the 
buildup factor of lead glass (treated as a compound of lead, oxygen...) is 
quite different from the stored values for lead glass. I could not find what 
their calculation is actually doing.

So, I am interested in: what is MicroShield doing when it calculates buildup 
factors for compounds and is there an accepted method for doing that.
