ABSTRACT:
The invention is a digital radiation detector utilizing the stable timing functions of a microcontroller or plurality of microcontrolling devices to perform three independent functions. A first timer generates a continuous square wave output that is fed through a class B amplifier to yield a stable, drift-free power supply for a connected radiation sensor. A second timer is used as an event counter for counting the processed pulses coming from the radiation sensor. A third timer acts as a real time clock generating a one-second interrupt for quantifying the number of counts per second. The number of counts per second can be communicated as raw data through a communication interface or presented as a number of audible or visual displays.
