Radiation
- Two Radium-containing clocks I found at a flea market
I purchased a pocket-gamma spectrometer last week (Radiacode 102) and brought it with me to a local flea market to find some radioactive antiques! I also found a radioactive gimbaled compass in a box, but did not buy that one.
Here is the processed Gamma spectrum measured with the Radiacode:

- 10 000 Muons hitting every square meter of Earth
I recently found out that 10 000 Muons are hitting every square meter of Earth a minute. They are created by high energy collisions in our upper atomsphere that then fly at nearly the speed of light down to earth and survive even though they have a short half-life because of relativistic effects slowing down their decay.
It's crazy to think that natural radiation can include strange unstable sub-atomic particles, not just alpha, beta and gamma radiation.
