| | | 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).
