I-131 Therapy Dose Limits

[772EAR@delphi.com]

I am asking the following for my counter part in Europe:

1.  Has the NRC open-source radiotherapy limit for I-131 in the been
raised to 100 mCi from 30 mCi? 

2.  What are the maximum allowable doses for open-source radiotherapy in
the USA?

3. How many hospital centers in the USA exist with isolation room
facillities?

3. Is there a number for the total isolation rooms available in the
USA?

4. What are the patient release criteria in the USA, once these patients
received high-dose radionuclide therapy?

Thanks in advance for responses to these queries.
