RE: Alarms at Borders
We (Nevada Test Site) see quite a few every quarter, some identified by the
worker coming to us ahead of the procedure, and the rest by TLD readings or
gate alarms. We have gotten fairly adept at identifying various medical
procedures from the signature response patterns they cause on the dosimeter.
A surprising percentage of those identified by dosimetry were never told by
the medical system that radioactivity was involved. The problem that causes
is our problem - not the patient's. As far as I can see, it really makes no
difference to the patient. But that's changing.
People set off alarms at various locations here following these procedures
(mostly stress tests, bone scans are a distant second). So patients who
work here experience a result that others don't. With the advent of more
and more detectors around the country, the patient will be impacted more and
more. Being held at a border station so as to harm someone's travel plans
is not what the medical community should be doing to its patients. So the
harmless practice of not informing the patient is beginning to have a
somewhat harmful effect. Eventually, public pressure will solve this
problem.

Hi All,
I have been following this thread with interest. We also have experienced a
number of issues with our own workforce. Being a small area, I was able to
contact those 3 facilities that administered nuclear medicine treatment and
talk to the nuclear medicine technologists. Now we don't have too many
surprises.
It seems to me that this is an area where HPS and AAPM can help. I have
initiated a discussion with the HPS about trying to "solve" at least this
little piece of the problem. We ought to be able to use our two
organizations to come up with some type of informational form that nuclear
medicine providers could use that can be adopted for use in the US at least.
Some type of authentication method would probably have to be developed, but
at least it would be a start.
Happy Thursday All,
Linda
