"Whole-body radiation exposure after a typical dose (2 to 4 mCi) is
approximately 0.68 rad, and the kidneys are the organ exposed to the most
radiation. The relatively long half-life (T1/2=73 hours) and low energy of
201Tl are important considerations during imaging. The long T1/2 contributes
to its significant inpatient residence time and requires lower doses to
minimize risk of radiation exposure."

This kind of event happens regularly. Many years ago, a visitor on a tour of
the White House [when the public was taken on tours]  set off rad monitors
there because he had had a nuclear stress test.

The article at the link Joel supplied below also states:

"In the test, a small amount of a radioactive material is injected into the
veins and used to help track blood flow to the heart.
Though the amount of radioactive material used in the test is relatively low
-- equal to a few X-rays or a diagnostic CT scan -- it was enough to set off
a radioactivity detector in the state police car. "

As we know a "small amount" of radioactivity or dose is relative. Had a
release [ aka "spewing" as invariably used by the press in writing about any
release] from a nuclear plant like Millstone nuclear station in CT [ which
supplies power to over 1 million people in CT] resulted in a fraction of the
exposure and dose rate cited, even to one person, many professional
anti-nuclear scaremongers would be calling for shutting down every nuclear
plant in the region and be wearing out the word "Fukushima". "Ain't it
awful" :-)

 "Mike Apatow, of Milford, poses at Stratford Fire Station, Company 2, in
Stratford, Conn. May 10th, 2012, where he works as firefighter. Apatow, who
had a radioactive stress test Wednesday, was pulled over later in the day,
in Newtown, by a state police trooper after a radioactivity detector in the
trooper's car was set off when Apatow passed. The detectors are used to help
identify potential terror threats. Apatow was not on duty at the time.
