Abstract
The device and method for triggering a random event is suited for use as an RPG in a Packinko gaming machine and involves the use of a radioactive source and detector. Repeated measurement of decay events detected by the detector during selected time periods are compared against one another and preferably against a predetermined number and a win event is triggered when the numbers are equal. Appropriate selection of the predetermined number for comparison determines the probability of a win event being triggered. With this device and method materials having very low radioactivity may be used. Also, the device and method operates to trigger a win event at a desired probability without the need for the Mean output of the radioactive material to be measured accurately.
