I think you misunderstood what he said (as usual) Bill. The kind of 
exposure is also highly relevant. Most notably ingestion as opposed to 
simple proximity to the source. You are aware - I assume - that different 
modes of radiation (eg. alpha, beta, gamma etc.) have different 
penetrative qualities and whilst lead is required to screen out some 
types, others can't even make it through skin.
