Periodic Table of Tools Poster by Theodore Gray (36x20 in.)

Yes. The uranium, thorium, and radium cubes are all sealed in acrylic, which contains any meaningful exposure. The radium sample specifically emits less radiation than you'd get on an airline flight, and even carrying the uranium sample in your pocket every day for a year wouldn't add up to the dose from a single medical scan. The Heritage Periodic Table follows the same standard: it's built to be safe to handle and store, and it deliberately leaves out the more dangerous radioactive elements like polonium and everything heavier, along with technetium and promethium.

Yes. The uranium sample is a naturally occurring mineral (autunite), which puts it in a license-exempt category under federal radioactive material rules rather than something restricted. The radium sample is sourced from an antique, which is part of why it can be shipped legally, including internationally. If you're outside the US, it's worth checking your own country's import rules since classifications vary.

It contains 83 real element samples embedded in acrylic, essentially every stable element collectible in solid form. A handful are deliberately excluded for safety or rarity reasons (the heavier radioactive elements past thorium, plus technetium and promethium), so what's left is the full set that can be safely handled and displayed.

Yes. These are sourced from a specialist manufacturer that hand-prepares real element and mineral samples, verified for purity, before sealing them in acrylic. That's also why a few, like the uranium sample, carry the standard radioactive-material notice: the radioactivity is real, not simulated, though it's well within safe handling limits.
