...much harm wasn't clear until last week, when a team of scientists at Columbia University reported in the journal Radiology precisely how much radiation you are exposed to in a single full-body scan. It turns out to be 100 times the radiation dose of a typical mammogram--or roughly equivalent to that received by Hiroshima survivors 1.5 miles away from the center of the atom bomb blast. According to David Brenner, lead author of the study, the risks associated with just one scan are relatively modest, likely to increase your chances of dying from a radiation-caused cancer...
...DRUGSTORES In a number of cities, CVS is trying out kiosks that let customers scan their items and then pay with cash or a credit or debit card. One downside: the kiosks can't be used to ring up prescription drugs. Osco and Sav-On are running small-scale tests...

DIED. SIR GODFREY HOUNSFIELD, 84, British electrical engineer who invented the C.T. scan, a diagnostic tool that revolutionized medical care; in London. In the 1960s he built the computerized axial tomography scanner, which uses X rays to give doctors a three-dimensional, cross-sectional view of the body's interior. The innovation brought him the 1979 Nobel Prize, which he shared with South African scientist Allan Cormack, who had worked independently on the idea...
