| attribute | radon | comment | String | The PMEL radon instrument is a "dual flow loop, two filtered radon detector". The general features of the instrument are described in Whittlestone and Zahorowski, Baseline radon detectors for shipboard use: Development and deployment in the First Aerosol Characterization Experiment (ACE1), J. Geophys. Res., 103, 16,743-16,751, 1998. The instrument response is due to radon gas, not radon daughters (all of the existing radon daughters are filtered out before entering the decay/counting tank). The instrument registers the total number of decay counts per 30 minute interval on a filter (wire screen) arising from the decay of radon in the tank. The volume of the decay/counting tank was 905 l and the sample flow rate into and out of the tank was typically 70 l/min. The response time of the radon instrument is limited to about 30 minutes by the radiological decay time constants of the radon daughters on the wire screen filter. Thus, the start time given in the data file is 15 minutes prior to the midpoint of the counting interval. The instrument was calibrated with a known radon source in Seattle before the cruise and a second calibration was performed after the instrument was shipped back to PMEL. Radon concentrations are given in mBq m-3. |
