Study: U.S. needs better ways to evaluate radiation detection systems
Current radiation detectors placed at U.S. ports cost about $82,000 each and have a high false-alarm rate; DHS wants to buy 800 new detectors, at a cost of $360,000 each, but lawmakers and experts say that before this money is spent, there should be a better way to evaluate the effectiveness of the new systems

TSA lab's new concept in airport security: Tunnel of Truth
Futuristic vision of airport security would see passengers stand on a conveyor belt moving under an archway as different sensors scan them for weapons, bombs, and other prohibited items; no need to take the shoes off; by the time they step out of the tunnel, they have been thoroughly checked out

Scientists urge U.S. to stop using caesium-137, a dirty bomb ingredient
About 1,300 machines at U.S. hospitals and universities used for irradiating blood for transplant patients and other purposes contain caesium-137; individuals or groups eager to detonate a dirty bomb in a U.S. city could steal this caesium chloride and combine it with conventional explosives such as dynamite to produce a dirty bomb or radiological dispersal device

Analysis // by Ben Frankel: U.S. still fighting for sanctions on Iran, but with a weaker hand
The Bush administration shot itself in the foot by releasing a confusing and partially misleading intelligence assessment of Iran’s nuclear weapon activities; the administration dealt a near-fatal blow to the effort to intensify economic sanctions on Iran, instead creating a situation in which the world will either have to accept a nuclear-armed Iran or go to war to stop it
