Two sources of information may be useful to you:

a.  Schien.  "The Health Physics and Radiological Health Handbook."  
pp. 527 - 542.  [Gives tables of beta dose rates, and other useful 
data].

b.  Cember.  "Introduction to Health Physics--2nd Edition."  p. 99.  
[Gives a "range in air" table.  While not "dose" per se, it does let 
one get a feel for relative hazard.]

c.  Atomic Energy of Canada.  "Tables of Beta-Ray Dose Distributions in 
Water, Air and Other Media."  Sept, 1982.  [Appears to be source of 
tables for (a), however has much more detail.]

If you don't have this handy, please let me know a FAX number, and (as 
schedule permits) I will try to get the pertinent data to you.

Hope this helps.
