*The EcoGammas are sensitive electronic devices that can experience intermittent malfunctions and/or interference; this typically results in characteristic positive and/or negative data spikes. These aberrations are removed from the data set based on the judgement of the data analyst. **The range of background exposure rates from EcoGamma data collected to date is approximately 9 – 34 µR/hr.
