Underwater environmental measurements at Krasnohorska cave (Slovakia)

Measurements of underwater gamma radiation and environmental parameters performed at Krasnohorska cave (Slovakia) during a field campaign in the framework of PT-SK bilateral project RADCAMIN (RADon in Caves and MINes – Portuguese and Slovak case studies). The high-resolution measurements (every 1-second) are performed with an innovative sensor developed by INESC TEC in order to be able to measure gamma radiation underwater, at depths of at least 100m.

The data are stored in individual files for each hour, named ddmmyyHH.TXT (where dd represents the day of the month, mm the month, yy the last 2 digits of the year, in this case 19, and HH the hour. Each file contains 6 columns, corresponding to the date (in the dd/mm/yy format), the time (in the HH:MM:SS format) the gamma radiation counts, the voltage (multiplied by 1000) the pressure in hPa (multiplied by 10) and the temperature (in deg Celsius, multiplied by 1000).
