Data from underwater gamma radiation monitoring

Data from underwater gamma radiation measurements under controlled conditions (ongoing monitoring).

The measurements are performed with the purpose of studying background gamma radiation under stable environmental conditions. The fact that measurements are performed underwater (in a research tank, at a depth of about 2m) reduces environmental fluctuations (particularly temperature) and also removes the contribution of terrestrial gamma radiation, enabling to measure the gamma radiation background and the cosmic radiation contribution.

Each individual file contains 1 hour of measurements every 1-second. Data are organized in 6 space-separated columns, corresponding to date (dd/mm/yy), time (HH:MM:SS), gamma counts (counts per second), battery voltage x 1000 (V), pressure x 10 (mbar) and temperature x 100 (degree celsius). Each individual line of the datafile ends by a comma. Files for each month are made available as compressed files.
