Hi John:

I, too, remain ignorant of many things...

I recall that in the immediate aftermath of the Chernobyl accident, beta
burn on skin, and I presume in the lungs, was an important consideration
along with total gamma dose for the ultimate prognosis of first responders.
 The effect as described to me was much like a thermal burn to the patient.
In the discussion that I heard, it was the combination of severe beta burn
and gamma dose that caused death.

I would tend to agree that beta burn to the lungs may be neglected if using
SCBA.  In the discussions that I heard, 10th Anniversary meetings of the
Chernobyl accident in Minsk and the 10th Anniversary meetings at the IAEA,
Belarus, aluminized Mylar was thought to be sufficient to prevent beta burn
on skin.

But that's all second-hand information.
