Because it is radioactive!
without using any radioactive materials , you can use tonic water in a jello recipe that will make it glow under black light that all i know :/
Most radioactive materials in mineral collections are Uranium minerals. The Uranyl ion produces minerals with characteristically yellow/green, acicular, crystals that can be very attractive.
These materials absorb light energy in the day and they are able to give off this energy in the dark or at night. Some examples of these materials are glow in the dark stickers, glow in the dark watches and glow in the dark bouncy balls.
Hydrogen is not radioactive.
No. They generate light by a process of chemical luminescence and contain no radioactive materials.

No- but it looks good in the comics. Most radioactive waste does not glow in ANY color. Very high level radioactive may exhibit Cherenkov radiation effects, and glow blue or purple.
Minerals that glow in the dark may or may not be radioactive. There are some other reasons that a mineral could glow in the dark without it being radioactive. Certainly if a material is radioactive enough it will glow in the dark. But note that some radioactive materials are only weakly radioactive, and an observer will not be able to see them glow in the dark.
Severe misunderstanding.Early radium dial watches and instruments glowed green where the "radium" paint had been applied. People assumed that was the radium glow. Actually radium does not glow at all, what gave the green glow was a phosphor (not phosphorus that is an element that burns easily, phosphors are compounds that glow when "excited" - the brightest and cheapest phosphors glow green) excited by the radiation emitted by the radium.The X-ray Fluoroscope used a phosphor screen that glowed green when excited by the X-rays.So people then assumed anything radioactive glowed green. (I almost wish, but humans have no sense that can detect radioactivity.)Hope that helps.
If it isn't giving off a glow, it might not be radioactive. It will glow because most, not all, radioactive material always glows.
Yes. Radioactive substances glow .

Radioactive
they both glow.
In that case, the radioactive materials will pollute the atmosphere.
Not if it is radioactive or you are an alien
