Between 1950 - 1951, children could get the Gilbert U-238 Atomic Energy Lab. A radioactive atomic energy lab kit which came with three sources of radiation, and four uranium ores. It allowed them to make nuclear reactions at home and was removed from shelves in 1951. pic.twitter.com/K0GWz3wObM

That was Clarks. You could see the bones in your feet to see if they were ‘compressed’.
You could obviously feel that anyway, but the machine was very popular, especially with children.
They were known to be dangerous, but they were certainly still in use in the early 1970s.
