Scheduled Calibration Tests

Calibration response tests of the ion chambers located at the CEMP stations will occur according to the following schedule. These calibration checks will result in brief spikes in gamma radiation readings, and are not related to actual increases in background radiation. These calibration response spikes will be subsequently removed during regular quality-assurance checks of the data, so as not to skew data averages.

Note: Scheduled field checks are now on a quarterly schedule until further evaluation.
