Abstract
A method and apparatus in accordance with the present disclosure relate to monitoring gain of a proportional counter. The method includes generating a pulse height spectrum of the proportional counter, defining a first window and a second window within the pulse height spectrum, counting electrical pulses outputted by the proportional counter within the first window of the pulse height spectrum, thereby defining a first window count, counting electrical pulses outputted by the proportional counter within the second window of the pulse height spectrum, thereby defining a second window count, and determining a difference between the first window count and the second window count.
