[ RadSafe ] short half life

[Dixon, John E. (CDC/CCEHIP/NCEH)]

Regarding this issue, from my
experience it is facility specific and  confusing. 
 
Regards,
John

I have seen  both 90 days and 120 days spelled out as short lived isotopes on
NRC and  Agreement State Licenses. Also I have seen facility specific
examples  in procedures.  Back in the moratorium days on DOE sites I remembering 
auditing and seeing lists in procedures specifying short lived  radionuclides
with ranges of 30 days to anything less than 1 year.  I  have also seen research
facilities using any isotopes with a half-life less than  30 days (e.g my
graduate school) but the radiopharmacy school at the same  university used a
different list and they both operated under the same  license.  So from my
experience it can be facility specific and  confusing.
