I read somewhere that the Curies would go out to their workshop after dark and just stand there watching the entire room glow. There were glowing rings on the shelves where bottles had been sitting at some time in the past, who knows how long ago. > On Oct 26, 2020, at 6:00 PM, Paul Andrews <[email protected]> wrote: > > I have a couple of old alarm clocks with radium dials.

My entry-level scintillator gives me a background of ~1150CPM at 900V. My dad had prostate cancer a while back. They implanted something with a half-life of two or three weeks. I checked him every half-life to confirm that the count had in fact decreased exactly 50%. 8D Terry Bowman, KA4HJH "The Mac Doctor" Q: Should car stereo speakers be pointed to the rear for more thrust or up for more traction? A. On long trips, the 20- to 30% improvement in gas mileage you might get with speakers pointing to the rear is certainly worthwhile. On the other hand, if you drive on snow or ice, the extra traction of speakers pointing upward gives you added control.
