  • Page 2 2. General Information “Dosimetry” means measuring radiation levels specifically in the context of human health effects. The Better Geiger S-2 uses a solid scintillator sensor primarily designed to measure radiation dose rate. Except for very specialized applications, dosimetry only involves X- ray/gamma measurement and not alpha/beta measurement because alpha/beta radiation is typically not an external hazard.
  • Page 3 3. Technical Specifications Best estimates subject to change (10 µSv/hr = 1 mrem/hr) • Power supply: 2x AA batteries, accepts all standard types including rechargeable, typical life >50 hours in normal display modes, >95 hours in dark mode • Minimum sensitive energy: 50 keV •...
  • Page 4 4. Basic Operation Buttons: The device has six buttons. The top left controls power on/off. The top middle cycles through display modes. The top right turns the clicking sound on and off. The bottom middle is used to access detector settings. Other button functionality is explained on the display when appropriate.
  • Page 5 Alarms: One alarm is “rate” alarm and will be triggered when the dose rate goes above a given threshold. The “rate” alarm will beep until confirmed by pressing the > button. If the rate drops below the alarm threshold and then goes back above it, the alarm will trigger similarly again.
  • Page 6 5. Display Modes Mode 1: Top line shows BATT:OK to indicate that battery status. The top right indicates ALARM: then RATE/SUM/NONE/BOTH depending on which alarm(s) are active. The lower left indicates qualitative dose rate RANGE (“NORMAL”, “HIGH”, or “DANGER”). Bottom right indicates unit of µSv/hr and main number on display shows dose rate.
  • Page 7 6. Understanding Display Numbers Counts per minute (CPM) gives the raw rate of detected interactions in the scintillator. Incoming X-ray/gamma photons can have higher or lower energies, but the CPM value only counts interactions. Radiation dose is a unit related to the health effect on the human body of radiation.
  • Page 8 All people are exposed to background radiation from natural and unnatural sources. The amount can vary widely but 2,000-3,000 µSv per year is common. At the time of writing this document, in the US the annual whole-body limit allowed for workers exposed to radiation is 50,000 µSv.
  • Page 9 7. General Tips To measure general X-ray/gamma dose rate levels in a uniform radiation field, the detector orientation is typically not important. If there is a strong point-like radiation source then the detector response will strongly depend on distance from the source. This is because the intensity of a radiation field coming from an X- ray/gamma source tends to decrease roughly according to I=1/D where “I”...
