Certain isotopes are unstable and undergo a process of radioactive decay, slowly and steadily transforming, molecule by molecule, into a different isotope. This rate of decay is constant for a ...

It comes to us from [Science Shack] and uses radioactive decay to generate truly random numbers, as opposed to the pseudorandom number generators baked into most microcontrollers. The design is ...

This is done by choosing isotopes that: The half-life should be long enough to produce useful measurements but short enough for the radioactive sources to decay ... left in a person’s body.
