[uvawnleg] Game about radioactivity

The various probabilistic decay modes of radioactive isotopes seem like they could be the basis of a probabilistic game, perhaps gambling.  Decay should be simulated by a randomizer calibrated to the scientifically measured or predicted probabilities, or perhaps use fake probabilities to make the game more interesting (perhaps making more frequent extremely rare transitions).  Or time warp, allowing events that take a long time to occur.

Incidentally, how well developed is the theory predicting half lives and decay probabilities?

Spontaneous fission is messy.

Part of an idea: a roulette-like table marked with the table of isotopes onto which one can bet that a certain daughter isotope will eventually occur.
