[ RadSafe ] Beta emitters and external risks

[John Jacobus]

Question:  Would you say that beta emitters pose an
external radiation hazard or risk?  I am not consider
skin contamination.

Are there any (other) beta emitters that you would
consider to be a significant external hazard? 

What is your criteria for this judgement?

(Background:  I would in a medical research facility,
and we require beta shields for work involving large,
e.g., 10 mCi/370 MBq, amounts of P-32.  Are there
other beta emitters we should worry about?)

On Oct. 5, 1947, in the first televised White House address, President Truman asked Americans to refrain from eating meat on Tuesdays and poultry on Thursdays to help stockpile grain for starving people in Europe.
