Atomic bombs and nuclear reactors were dominating the headlines — and apparently that made it the perfect time to pick up an experiential uranium kit for kids.
Wait, what?

As insane as it sounds today, when nuclear processes take place deep underground behind lead-lined walls, this was exactly the situation in the early 1950s.
It was an era when everyone was captivated by nuclear power as the new wonder that would solve humanity's energy problem, and there was still no widespread awareness that radioactive materials could cause cancer.
The kit pictured was called the **Gilbert U-238 Atomic Energy Lab** (named after the common isotope of uranium). It contained a radioactive experiment set designed for children, and it is considered one of the most dangerous toys in history.
Inside, you could find sources of alpha, beta, and gamma radiation — including samples of uranium ore, lead, and zinc.
For detection purposes, the kit included, among other things, a Geiger counter and a cloud chamber, along with an instruction booklet for conducting experiments and background reading on the subject.

Fortunately, the kit was a commercial failure due to its high price — $49.50 (roughly $630 in today's money) — sparing many American children from exposure to these hazardous materials.
Further obstacles included difficulties sourcing the materials required for the kit, as well as growing government restrictions as public awareness of the dangers of radioactivity increased.
In total, fewer than 5,000 units were manufactured, and production was discontinued in 1951 — after less than two years on the market.

In 2024, one such kit sold at auction for $16,500 — 333 times its original price.
A re-examination of the kit revealed that the actual danger it posed was lower than previously thought, since the quantity of radioactive material it contained was very small.
Even so, it's safe to say that none of us would want to see a toy like this in our child's bedroom.
