  1. #Radiation measurements on a recent #flight I was on, it is interesting to see that immediately after takeoff, the rate drops significantly and only goes up higher again once you gain altitude. I guess it's due to the proximity to the ground and all that concrete and #rock #geology near the surface and then the #CosmicRays in the upper #atmosphere.

    There was one #HighEnergy event on the next flight. Probably due to a cosmic ray.

  2. My gamma spectrometer arrived yesterday. Unsurprisingly but thrilling, the smoke detector has Americium-241, which falls off to background levels (160 CPM) a half a meter away. Nothing else has shown gamma activity. I have some small element samples on order that should be interesting. I am curious whether it's worth it looking for thrift shop finds (uranium ceramics, radium watches) or if they are all routinely screened these days. #science #radioactivity #gamma #americium #uranium #RadiaCode
