Abstract
A random number generator based on naturally occurring events in which directional randomness of radioactivity is exploited to generate a random number sequence. Radiation emissions from a radiation source are detected at different spatial locations about the radiation source. A unique numerical value is assigned to radiation detected at the different spatial locations. A random number sequence comprising numerical values is generated depending upon which spatial location radiation is detected.
