Averaging is the process of combining radiation measurements over a period of time to produce a more stable and accurate reading.
Instead of showing every individual count (which fluctuates randomly), the detector displays an average of recent readings.
Why Averaging Is Needed
Radiation is inherently random.
Even at a constant radiation level:
- The detector may count 10 events in one second
- Then 3 events the next
- Then 12 events after that
This randomness is called statistical variation (Poisson distribution)
Without averaging, your display would:
- Jump up and down constantly
- Be hard to interpret
