Uranium Radioactive tiles at a grade school
Radioactive tiles at a grade school. (External Sample)
These are pretty art-deco style decorative tiles behind the drinking fountains at my children's 1920's era grade scrool. They read about 4000 counts per minute on my alpha-beta-gamm Geiger counter due to the use or uranium in the glaze (similarly to the way uranium was used in Fiestaware dishes for decades).
