[ RadSafe ] Portal Monitors in Emergency Area

[Jim Hardeman]

Oh, if it only were that simple!! Yes, having data from all of these
monitors on a map would be GREAT, but using that data to "triangulate"
is somewhat akin to using field monitoring data to back-calculate a
source term from a release ... works well in theory, but in practice,
the data are never as clean as they are during exercises.

We have a bunch of hospitals in the NYC area. I
figured the reponse from multiple ED monitors could be
used to triangulate an RDD event. If you could
geographically map the signal from all the portal
monitors at ED's in NYC, for example, you could easily
get an idea of the "hot spot" of an event. It would be
like having a geographic nucmed uptake scan with
"uptake" to the "ED organ" (you could talk about
"excretion" for waste monitors too). I wrote a web
interface to such a thing (using Apache and PHP and
timed update scripts to Ludlum 375 data) and presented
it at the 2004 RSNA with hopes of getting more sites
(outside of our hospital group) to volunteer their
data by allowing the installation of timed network
script. I'm getting 12 dual detector 375's with web
cameras (to take snapshots of the scene at time of
alarm) for my specific hospital alone. More hospitals
are getting them. If you are interested in possibly
participating, do contact me.
