Nuclear Radiation Detectors from Cell Phones?

Well, Jack Bauer would like us to believe that nuclear terror is just around the corner, and with this system, we could just possibly prove it.

Researchers at Purdue University are working with the state of Indiana to develop a system that would use a network of cell phones to detect and track radiation to help prevent terrorist attacks with radiological "dirty bombs" and nuclear weapons.

Such a system could blanket the nation with millions of cell phones equipped with radiation sensors able to detect even light residues of radioactive material. Because cell phones already contain global positioning locators, the network of phones would serve as a tracking system, said physics professor Ephraim Fischbach. Fischbach is working with Jere Jenkins, director of Purdue's radiation laboratories within the School of Nuclear Engineering.

Interesting, but we'll withhold judgment until further testing is done.  No sense giving this a glowing review too early!
