Study of U.K. nuclear power plants employees reveals radiation risks
More than 65,000 individuals were employed between 1946 and 2002 at nuclear power plants operated by British Nuclear Fuels plc and its predecessors; a team of researchers studied the health histories of these individuals, and found evidence for an association between mortality from noncancer causes of death, particularly circulatory system disease, and external exposure to ionizing radiation

TSA tests ferry radiation sniffer at Galveston
Tests began last Thursday; equipment was able to find small amounts placed in TSA vehicles; each sniffer costs $150,000, and are sensitive enough to detect the radiation in someone who has been injected with radioactive dye for a medical procedure two weeks after the injection

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
