  1. Under the "normal" conditions, no influence at all.

     

    Then, you can use heavy means. If you bombard 14C with 10TeV protons it will break, but (*) that's cheating (**) it's not radioactivity (***) any nuclide would break.

     

    Somewhere in the middle:

    - One beta minus emitter (forgotten which, the experiment wasn't with 14C) decays much faster if the atom is completely stripped from its electrons. The emitted electron jumps to the then available 1s orbital, through a tunnel length and depth more favourable than to vacuum.

    - An absorbed gamma ray that excites 14C will necessarily change the decay rate. Half-cheating again, as people consider the excited nuclide is no 14C any more.

     

    Not at beta emission, but electron capture: one paper claimed an increase in electron capture rate at sonoluminescence, but this has never been observed by the other teams and is widely considered a mistake.

    Thanks for the replies.

     

    I had an argue with religious Jew about the age of Earth.

    He told me that carbon 14 dating can be cheated.

     

    I guess from the method you suggested it will be very easy to discover manipulation.

     

    However Suess effect can indeed influence the accuracy of the radioactive dating.

  2. Hi

     

    I need to use excel or any type of spreadsheet to calculate my work hours.

    In other words I need to calculate how many hours did I work.

     

    Anyway I used excel in one square I write the time that I begin, like for example 5:30, in other square I write the time I finished to work like 14:00.

     

    Now what function can I used that it will calculate that time that I worked in hour unit.

    So that in the case of the example it will give me 8.5 hours.

     

    Thanks for the help.
