Re[2]: Therapeutic I-131 waste

The NCRPs may be resident to the USA, but are they not standard health physics 
practices.  It doesn't make a difference where you are located.  Good standard 
health physics practices can be implemented anywhere...mike coogen sends

Most such patients treated at Ohio State during the early 1990's showed a 
mode half-life of about 19 hours.  (I ought to know, since I surveyed them 
enough!)
     
You other guys - I don't think referring to NRC regs or NCRP publications is 
at all helpful, since those are specific to the USA.  The person asking the 
question is in GREECE.
     
For that matter, he never mentioned what he meant by "tackle the problem". 
Which problem?  Are you just asking permission from local authorities for 
sanitary sewer disposal, or are you about to start collecting data/samples 
for an original research project?  (I hope for your sake it's the former.)
