    Hey, Physics World has http://images.iop.org/dl/physicsweb/PWDec07quiz.pdf" [Broken] from 2007. There's a £50 prize for someone who gets most of the answer.

    Wouldn't it be nice if a PF member wins this? :)

    I've got the answer for "B" at the top of the page concerning this sign:

    http://www.iaea.org/NewsCenter/images/newradiationsymbol_300x200.gif [Broken]


    The image in the top portion of the triangle is a fan blade----these signs are in public bathrooms. So the sign indicates, if the fan isn't working---it's best to leave at a fast pace!

    B.
    The symbol is intended for IAEA Category 1, 2 and 3 sources defined as dangerous sources capable of death or serious injury, including food irradiators, teletherapy machines for cancer treatment and industrial radiography units. The symbol is to be placed on the device housing the source, as a warning not to dismantle the device or to get any closer. It will not be visible under normal use, only if someone attempts to disassemble the device. The symbol will not be located on building access doors, transportation packages or containers.
