[ RadSafe ] SCBA and beta dose connection?

[radbloom at comcast.net]

John, 



While I'm not sure it's always true, many SCBA models includes a full-face shield, which would significantly reduce or eliminate (depending on beta energy and shield thickness) beta dose to the eyes/face.

I have a document in front of me that states, " IF SCBAs are used, the 
beta dose rates may be neglected."  The context is in a post -accident 
mission dose determination where the effect of SCBAs is discussed. I'll 
admit my ignorance on this one.  Does anybody know where this came from or 
what would support it? 

thx in advance  - -jmr
