Detecting ANTIMATTER in food - DIY Gamma spectroscopy

It may seem strange, but everything you've ever eaten contained a tiny amount of antimatter. In this video we explore how it's produced, what happens to it, and how we can detect it. We build a gamma ray spectrometer and use it to detect the antimatter in common materials.

I'm the head of a radiochemistry lab in Australia where we have 9 HPGe Gamma spectrometers. When I went for the job interview there a while back, the at the time lead physicist went over the different counting systems and showed me one of the typical gamma spectrums. I was amazed to see a 511 keV peak so clearly, as it is in effect, indirectly measuring the existence of antimatter. Even with no samples in the detectors we always see a clear 511 keV peaks in the background due to single photon escape events from the surrounding castle material. Even thought I see them every day, the idea behind what we're actually measuring is still so cool to me.

What do you mean ? What experiment would you like to do ? I don't think the double slit experiment has anything to do with particle's quantum properties like charge or spin.

Just the analysis of scattering. Not sure if compton scattering is applicable here. But lets say we find the super symmetry of an electron can we then use bosons to alter its charge by changing its mass orbital or what its orbiting what ever its axis is. To somehow swap charges. Way out of my skill but im thinking if we can somehow change the charge to positive we could make heavier anti elements maybe..

@The Thought Emporium: Hello! I wanted to make a suggestion for investigation, given the current CV crisis, and ask that you take a look at sterilization of surfaces with UV light. There are a lot of grossly inaccurate marketing campaigns on amazon and ebay advertising UV bulbs. Among the ridiculous claims, for example, are bulbs with a specified wavelength of "UV Light", that UV in the above ~200 nm band produces microbe-killing ozone (sources I find say it doesn't), and in some particularly bad cases that black-light spectrum bulbs are "germicidal". Can you take a dive into this topic?

[@unkown9081]

agreed. it should be investigated

[@leocurious9919]

"(sources I find say it doesn't)" You have sourcves that say that UV is not capable of breaking the Bond in O2, thus letting O3 be formed? Please let me see that. O2 is photolyzed by light of 241 nm (or lower), since it has a bond energy of 498 kJ/mol. Any quartz UV-Lamp will do that and you will smell that.
