    You can increase voltage to reach 50 - 100mW power.
    Did you make another radiation measurements?

    magicsound Are you doing more tests? You can perform repeatable measurements after each activation while one day between measurements is fine.

    Yes, you can regulate lemons just by changing them for a new :)

    magicsound You can still use the cell for few more weeks. It should work well until there is enough water.
    Cell with D2O can yield very likely better interesting results but demineralized H2O is working pretty good for me.


    Side note - From my…

    I already identified that the cell is not producing any Gammas as far as I can measure. Background from NaI is still more or less constant.
    I already found that these are not high energetic photons with energy > 20keV.

    Pancake detector is much more…

    By the way there are traces of Palladium deep in the Sponge. But they are barely detectable. Peaks are visible but not identified.

    Yes, there can be contamination with Carbon as it is happening anywhere in the air.
    During analysis peaks from Cadmium, Chromium can overlap with other peaks and create false results. This was avoided during measurement.

    The sheet always delivers…

    For those not understanding EDX fully, there is plenty of Lithium/LiOD around. These are the crystals all around the Sponge.
    EDX has limitation that it can't sense Li and lighter elements, so it is just missing there.

    Here is the SEM/EDX report from the very first run Titanium Sponge, D2O, LiOD, Nickel. You can make your conclusions.

    It is possible that there are more particles types. So by shielding one type it could reduce count rate noticeable.
    From my experience there is direct relation between Pancake distance and activated material with respect to counts. Yes, I can also…

    magicsound Am I right that the paper you tested was 4mm far from the mica window?
    If yes then putting it closer will increase the counts A LOT.

    Thank you very much for your hard work!
    It is very appreciated and look to be promising. I will try to get the easiest and cheapest setup to detect the particles above any doubt. I think that this is the key thing in this experiment.
    I really have no…

    Interesting. I am doing always just one measurement per activation because it seems to me that the radiation source is somehow exhausted when doing a changes.
    But definitively it is still there even if wrapped in a conductive foil from both sides to…

    Hmm, so can you see is it elevated? Is it still over 60% from background? I mean 1.6 x background, right?
  • JohnyFive

    Post
    You can eventually measure the paper from both sides. And try to put it as close as possible.
  • JohnyFive

    Post
    Fingers crossed!
  • JohnyFive

    I am looking forward! The foils are not necessary, you should measure clearly elevated radiation almost instantly (within 2 seconds). So even without a foil there should be no doubt about the source.

    But regarding trying a foils you can rather change…

    Described behavior is likely same with mine observations. I also can confirm changes in resistance. So I am using constant voltage regulation always and change when needed.
    Also I can confirm water will change to white and then rather suddenly to black.…

    Thanks for interesting messages.

    From my measurements I have feeling that in order to pickup clearly elevated radiation (at least with Pancake) a movement is necessary.
    I tried to perform a static measurements as magicsound but it never turned out…

    In 2 weeks I will be trying new Si-8B and Si-14B from Ukraine. Background is around 120 CPM so very sensitive.
