Switzerland. I didn't find it in the wild, I went with Geiger counter to a mineral fair.

Got some recently too, surprisingly hot 50k counts per minute with alpha counter. Fun stuff.

LZ Sets a World’s Best in the Hunt for Galactic Dark Matter and Gets a New Look at Neutrinos from the Sun’s Core The LUX-ZEPLIN experiment analyzed the largest dataset ever collected by a dark matter detector, reaching unmatched sensitivity.

Today, researchers with the @lzdarkmatter.bsky.social experiment set a world's best in the search for galactic #DarkMatter, and also marked the detector’s first glimpse of neutrinos from the sun's core. newscenter.lbl.gov/2025/12/08/l...

Last week my colleagues and I visited the Bedretto underground lab, operated by the @ethz.ch (bedrettolab.ethz.ch/en/home/). For now, umbrellas
to protect our small neutron detectors were needed, but in the future we might outfit the deep tunnel (~1500 m overburden) for rare event searches ;)
