Elevation correction factors for E-PERM radon monitors
1Rad Elec Inc., Frederick, MD 21701.
Electret ion chamber (E-PERM) radon monitors require elevation corrections for accurate measurements. These corrections, determined experimentally, are minor but essential for readings taken at altitudes different from sea level.
Area of Science:
- Environmental Science
- Radiation Detection
Background:
- Electret ion chambers (E-PERM) are commonly used for radon monitoring.
- Calibration is typically performed at sea level, necessitating adjustments for other elevations.
Purpose of the Study:
- To experimentally determine elevation-dependent correction factors for E-PERM radon monitors.
- To assess the impact of altitude on the accuracy of E-PERM radon measurements.
Main Methods:
- Utilized three commercially available E-PERM models.
- Experimentally determined correction factors as a function of elevation above sea level.
Main Results:
- Quantified the necessary corrections for E-PERM monitors at various elevations.
- Found that these corrections are generally minor.
Conclusions:
- Elevation corrections are required for accurate E-PERM radon monitor readings at non-sea-level altitudes.
- Applying these corrections enhances the reliability of radon measurements in diverse geographical locations.
