    professor u know.. when i watch ur video then i become so much involved with it that when a send video peeps out on the side of the video i go to that after ending that one.. but after that i realised that i haven't commented the previous one.. but i am not willing to go back and waste my time... so i carry on......probably this the first comment to any of ur videos as far as i can remember i have watched 75 videos of urs approx..but i haven't commented any one of them....so apologies....for the largest comment.....

    My grandparents worked (and met) working at Oak Ridge in the days leading up to the Manhattan project, and one of them later died of cancer. Cool to see that the same facility is now using radiation to help cure cancer.

      Actually in this case it is air ionization. It is often mistaken for that, but this sample is active enough that it cases the legendary blue flash often mistaken with Cherenkov, but it is more similar to air sparks

    Please stop talking about Molten Salt Reactors unless you have a degree in the field. The internet is flooded with cheerleaders over a technology not a single one of them could explain.
    As far as using this as medicine, why not use a different isotope that's safer for the human body? Is it because of the economics? Taking nuclear waste and selling it as medicine because it "kind of works" seems incredibly immoral to me.

    yup this is the other benefit of breeding U233 from Th232 it decays down to Bi213 which is one alpha decay from stable Bi209. Fluid fueled reactors of the Fast U238>Pu239 and the Thermal Th232>U233 will not only bring us unlimited heat and electricity. They will give useful fission products and very low amounts of long lived waste. The targeted Alpha therapy cancer assassin is just cream on the top.

  • PalimpsestProd
    PalimpsestProd 5 days ago

    So if we start using molten salt thorium reactors we'll have millions of times more actinium than we need to treat all cases of cancer but because it's made by a slow, highly specialized, fragile human working in a highly radioactive environment it'll still be insanely expensive. Earth needs robots. Note to engineers, nobody needs plastic coated paper cups, everybody needs robots.

  • Lawrence D’Oliveiro

    7:26 Blue light ... is that Cherenkov radiation?

    • Christopher Willis
      Christopher Willis Day ago

      It is actually most likely air ionization which makes a similar glow.

  • Lawrence D’Oliveiro

    6:07 Even scientists are now abbreviating “millilitre” as “mL” instead of “ml”, I see. It isn’t just packagers of retail products (like shampoo) doing this any more.

  • Lawrence D’Oliveiro

    3:06 Consider: a similar thing could apply to anything currently classed as “nuclear waste”. At the very least, precisely because it is so highly radioactive, it gives off a lot of energy, which is currently going unused. So this idea that it needs to be locked away in some impenetrable, invulnerable vault for thousands of years just seems unnecessary, when future technological breakthroughs could very likely come up with an application for it within a matter of decades or centuries.

    2:39 I believe the term for the arms is “waldoes”, from the Robert Heinlein story.

    • TrickyNekro
      TrickyNekro Day ago

      +Christopher Willis Apart from various chemicals like growth suppressants, I thought that some type of chemotherapy included molecules that a slightly radioactive that get eaten by cancer cells and after some time essentially killing them from inside. Radiation therapy is done by a machine not a pill, guiding a high energy particle beam. And also, from what I remember this video was explaining just this. I do not confuse radiation therapy with chemotherapy, I just say in chemotherapy they use radioactive molecules, but that also chemotherapy is so destructive for the body because it also attacks healthy reproducing cells, like skin and hair cells , that it can not possibly remain a reasonable cancer treatment in the future.
