    How Long Can a Nuclear Reactor Last?  Nov 21, 2009
    With nuclear providing always-on electricity that will become more cost-effective if a price is placed on heat-trapping , utilities have found it is now viable to replace turbines or lids that have been worn down by radiation exposure or wear. Many engineers are convinced that nearly any plant parts, most of which were not designed to be replaced, can be swapped out. (Scientific American)

    Mammography Debate Puzzles Many  Nov 20, 2009
    Too many of the so called experts who support the USPSTF imply that radiation exposure is one of the significant harms.
