So while Sri Lanka clamps down on the use of mobile phones to prevent terrorism, researchers at Purdue University are working with the state of Indiana to develop a system that would use a network of mobile phones to detect and track radiation in order to help prevent terrorist attacks with radiological “dirty bombs” and nuclear weapons.
Such a system could eventually blanket the nation with millions of mobile phones equipped with radiation sensors able to detect even slight residues of radioactive material. Because mobile phones already contain global positioning locators, the phone-based network would serve as a tracking system, says physics professor Ephraim Fischbach.
Great.
Every single hospital’s X-Ray room just became an Al Qaeda hideout. One other problem of course – I doubt any deranged folks who actually went into the trouble of assembling and transporting dirty bomb or nuclear device, caught driving around say New York city are actually going to clamber out and hold up their hands when dozens of cell phone totting citizens point accusingly at them with their iPhones.
But I guess a radiation fighting, hazmat detecting, mobile phone sounds far more sexy.

I think this is great. We need more insite into technology. Thank you Purdue University for caring enough to research technology for the safety of people.
