External dose rate versus internal dose rate for all investigated samples.
External dose rate versus internal dose rate for all investigated samples.

The table contains: sample information (sample ID and sample name), the natural concentration of radionuclides 238U, 232Th and 40K. Internal alpha, internal beta, external and cosmic dose rates were added up to obtain total dose rates. The final row shows the average and the standard deviation for the suite of samples.

Sample ID Sample name 238U (Bq/kg) 232Th (Bq/kg) 40K (Bq/kg) Cosmic dose rate (Gy/ka) External dose rate (Gy/ka) Internal alpha dose rate (Gy/ka) Internal beta dose rate (Gy/ka) Internal dose rate (Gy/ka) Total dose rate (Gy/ka)
