Volume 3, page 351/353

They describe several examples due to cardiac investigation, and present
figures, doses and conclusions.

"As a result even under very restrictive assumptions the dose to the
environment caused by "radiating" patients are far below the limits set by
radiation protection regulations. There is no necessity to separate patients
from other patients in a special waiting area after the administration of
the radioactive agents. This result is confirmed  by studies of other
researching groups, Ref. [2,3]"

If you do not have or not find the procedures, please let me know, I'll send
by Fax
