Identifying the permafrost isotopic signal and assessing permafrost freezing age by radionuclides
We use Radium isotopes to assess the freezing age of the pore-ice water. Because of the effort required to extract sufficient amounts of pore-ice water, and due to the expected low activity (concentration), we use ratios of different Radium isotopes. These ratios can serve as a unique signal of t...
