[ RadSafe ] Outpatient I-131 Therapy under attack

Wed Mar 24 12:48:29 CDT 2010

My understanding has been that a large concern with these I-131 therapies, aside from the external exposure issue, is the potential for internalizing the radioactive material. Internal tissues lack the protection that skin provides.
This is especially a concern in children with their longer life horizon, which allows ample time for many cancers to show themselves.

When you have isotope deliveries after hours and on weekends, where do the
vendors bring the isotopes? Are they placing them directly in the hot lab?

This issue has just recently come up during a mock JCAHO inspection, and
they want us to create another storage area for the isotopes in the ER and
have the vendor bring the isotopes and pick up the old ammo cases in a
secure place in the ER. My concern is that this is just opening up another
"hot lab/isotope storage area" that has to be maintained as a secure area.
Then the technologists would have to run down to ER every day to pick up the
isotopes and bring down the empty cases that are to be returned.

Have any of you run into this situation? If so, how are you handling it.
Thoughts?

             More whining (in USA Today article) about the danger to 
children.  How many I-131 patients are around children, and for how long?

           Assuming that Peter Crane's 200 milliC is true, at an 
average distance of 15 feet, how many millirems would someone receive 
in eight hours?

TLDs and Direct Ion Storage very well to pulsed radiation. Electronic Dosimeters do not.

>From our experience of over 700 in-patients and 600 out-patients, we have
measured about 0.17 mR/hr/mCi at one meter after administration. That works
out to about 1.63 mR/hr at 15 feet from 200 mCi, and therefore about 13 mR
in 8 hours. The caution is that the exposure rate per mCi among a bunch of
patients can vary by a factor of 2 either way.
