Fact vs. Fiction
Two grams of
pure disbelief.
Science and history in the palm of your hand.
You read that right. A real 2-gram piece of depleted uranium metal. Not a joke, not a novelty, not illegal. Just one of the pieces serious collectors have been quietly stocking for years.
This vs. what you're imagining.
The uranium in your head is bombs and reactors. That is not what this is. Depleted U238 is what remains after the reactive isotope is pulled out for nuclear power. It is the sedate, chemically stable cousin, and the only version you and I can legally own.

The specimen
Uranium metal 99.9%, depleted U238
The two-gram entry point into ownership. Sealed for the shelf. Ready for the questions that follow.
- 2 grams of solid uranium metal
- Sealed inside a 6 × 25 mm glass ampule
- 99.9% depleted U238, non-fissile
Fiction.
The pop culture version. Confidently repeated. Almost entirely wrong.
"It'll make me glow in the dark."
Depleted U238 emits alpha particles, which cannot penetrate skin, let alone induce a soft green haze. The glow lives in cartoons and old horror films. The metal on your shelf looks like grey metal, and stays that way.
"Two grams is enough to give me radiation poisoning."
The glass ampule stops nearly the entire emission before it leaves the container. External exposure from two sealed grams of depleted uranium is a rounding error against the background radiation you already live in every day.
"TSA will arrest me if they find it."
Depleted uranium is legal to own. TSA screens for weapons and explosives, not periodic table specimens. That said, ampules are for the shelf, not the carry-on.
"You need a federal license to own uranium."
Not this uranium. NRC regulations allow anyone to possess up to seven kilograms of depleted U238 without a license. Two grams sits roughly three thousand times under that limit.
"You need a Geiger counter to store it safely."
A sealed ampule on a shelf needs no monitoring. The alpha radiation drops to background inside the glass, and background is what surrounds you anyway.
Fact.
The actual science, and the small print most people miss.
Uranium is older than the solar system.
Every uranium atom in this ampule was forged inside a supernova billions of years before Earth existed. With a half-life of 4.5 billion years, the specimen on your shelf will outlast the sun.
US law permits anyone to possess up to seven kilograms.
Nuclear Regulatory Commission rules allow private ownership of depleted U238 with no license required, up to seven kilograms per person. Two grams sits comfortably inside that ceiling.
Depleted uranium is a working industrial material.
The US Navy uses it as ballast in aircraft carriers. Hospitals use it to shield medical imaging equipment. Same alloy, different applications, quietly doing their jobs for decades.
A single sheet of paper stops the radiation.
Depleted U238 emits alpha particles, the largest and slowest form of radioactive emission. Paper stops them. The glass ampule around this specimen is roughly a hundred sheets thick.
This is where the periodic table ends.
Uranium is atomic number 92, the heaviest naturally occurring element. Everything above it on the periodic table was synthesized by humans inside reactors. You are holding nature's last word.
The history your collection is missing
Safe. Legal. 4.5 billion years of stories.
