How can such a small Geiger counter give an accurate reading at low dose rates but still respond quickly to high dose rates?
The GammaMaster uses an advanced algorithm to automatically adjust its response time between 2 seconds and 5 minutes. When the dose rate is a fraction of 1Sv/h, the GammaMaster averages the reading over several minutes to provide a more accurate reading. When the field is increased to a few hundred Sv/h, the GammaMaster will display the correct field within a few seconds. With the audio turned on, the frequency of the beeps is the most immediate indication of the strength of the radiation field. The GammaMaster beeps whenever a gamma ray is detected. How often does the GammaMaster need to be calibrated or source checked? The calibration of GammaMaster is not expected to drift over time and there is nothing that can be adjusted. Recommended calibration and source check frequencies depend on the intended use of the GammaMaster. If you want to use the GammaMaster for regulatory compliance, the time interval at which the calibration has to be checked will be given in your local regulations
