A method for electro-depositing a radioactive material onto a metal substrate is disclosed. This is particularly well-suited for true random number generators. The method includes (a) at least partially masking the metal substrate to expose a metallic surface on the metal substrate; (b) connecting the metal substrate to a cathode of a current source; (c) submersing the exposed metallic surface into a solution containing radioactive metal ions, wherein the solution is connected to an anode of the current source; (d) removing the exposed metallic surface from the solution; (e) removing the solution from the exposed metallic surface; (f) measuring the amount of radioactivity emitted from the exposed metallic surface; and (g) repeating steps (c) through (f) until the amount of radioactivity measured in step (f) stabilizes relative to a previous measurement.
