Polonium-210 produces alpha radiation, which can't penetrate the skin. It will kill you with cancer if even one microgram of the stuff gets in your body, but otherwise it's relatively harmless. [Edit 1: That being said, a small cereal toy like that is, uhh, ironic. Edit 2: Oh and apparently it dissolves in water :DDD]

Also with a half life of 138 days it's hardly "one of the most radioactive substances on Earth".

A shorter half life generally means it puts out more radiation per hour.

Yes, and 138 days is far from the shortest. Take Radon-220 for example. It can be found in nature in trace amounts, while having a half life of only 55.6 seconds, while Radon-222 has the longest half-life of all Radon isotopes at 3.8 days.

I bet it's in the top 10% by mass. That makes your objections wrong and silly, you will never recover from this embarrassment.

They're still trying to kill us, but back then they were doing it in totally rad ways like giving us toys made out of polonium .

Yeah but it was barely any. Your smoke detector is probably more radioactive than it was.

One is a children's toy that comes in food while another is a ceiling mounted device you almost never interact with.

From what I can find online, it wasn't in the cereal box. You had to send away for it with money and a box top.

Wait until you hear about bananas!

So what did this radioactive ring supposedly do? there had to be a reason that kids were excited to win one

The ring was a miniature spinthariscope.

When removing the red cap in a dark room, you could peer into a tiny viewing chamber and see flashes of light caused by alpha particles hitting a zing sulfide screen.
