Favourite thing I've learned in 2023: Rosenthaler Platz U-Bahn station in Berlin is entirely decorated with radioactive uranium glazed tiles.

@gigabecquerel visited with a geiger counter to check.

Attached: 1 video The whole fucking station is uranium glazed??? That must be tens of kg of uranium! Hot damn I almost didn't want to leave Edit: Fuck sake there are so many armchair experts here. NO, this is NOT dangerous! Radiation is all around you and so far you have done just fine surviving that. It's a nice color and an interesting historical fact, and that's all there's to it.

@jonty @gigabecquerel What unit of measure? 10 microSieverts is normal background radiation. 40 is a plane trip. 100 is a dental xray. 3,000 is a mammogram. 50,000 is the max allowable annual occupational dose.

@pattykimura @jonty @gigabecquerel it's a Geiger counter it measures "ionizing radiation" as activity in "counts/events per second" passing thru the area of the sensor tube. You gotta know what radiation you're actually counting to make an estimate for the energy dosage and then also take the larger volume of a human into account and also the absorption coefficient for "the energy" of the radiation. It's not entirely trivial. Better devices can probably offer a rough guess which is somewhat in the ballpark of the correct order of magnitude. My guess is that it's probably not terribly much as long as one doesn't live next to those tiles.

@missqarnstein @jonty @gigabecquerel My brother was (retired) Director of Radiological Controls for a US military site. We are the grandchildren of a woman who died at Hiroshima. Our forebears are from Fukushima. I'm afraid of a number of things, including heights and salamanders, I'm not afraid of subway tiles.
