This
sounds neat, but Labov's transition edge sensors are very small and must operate
very cold. Their claim to fame is extremely good energy resolution, which
translates to sensitivity with respect to discriminating closely spaced gamma
lines from background. Fewer photopeak counts are therefore needed to
identify a radioisotope, but the total interaction probability and the
peak-to-compton remain very small. Also, I don't know if the helium
refrigerator needed to cool the devices are included in the cell
phone.

L I V E R M O R E, Calif., April 18 - A cell phone that will be able to tell the difference between a "dirty bomb" and someone who's undergone radiation treatment is among the next generation of anti-terrorism tools being worked on by national weapons lab scientists.to have prototypes ready for testing within a few months and could have the devices ready for action in about two years.
