Forwarded: Dose Rates

[baumbaug@nosc.mil (Joel T. Baumbaugh)]

     I  concur  with  Michael  Coogen,  I  have  measured  "many"
persons  receiving  a "variety" of isotopes for a  "plethora"  of
reasons  (I  should have been able to get "Cornucopia"  in  there
somewhere!).
     I  have  found that you are better off measuring the  actual
dose  rate  from  each person on an individual person  by  person
basis.   There are so MANY variables (patient uptake  variations,
body mass of the patient etc., etc.) that this, IMHO, is the only
fail-safe way to be sure of surrounding dose rates.

     Post  Scriptum, remember to check all sides of your patient,
as  the  dose-rate  will  be different  in  different  directions
depending on which organ(s) the uptake has occurred in.

     I  have  been asked to calculate the external  (gamma)  dose
rate from
     patients  following  a  wide  variety  of  nuclear  medicine
procedures.
     While  there is a large amount of data, and methodology,  to
calculate
     organ  and/or  patient doses, I cannot find much data  about
the dose
     rate  from  them that others might be exposed to. (There  is
some limited
     data  in  NCRP  37, but it considers everything as  a  point
source and
     neglects attenuation within the patient's body.)

     Has  anyone  done actual dose rate measurements on  patients
after
     nuclear  medicine procedures? Is this data readily available
anywhere?
