[AHW24-P10] Estimation of excess air component in groundwater by using dissolved Argon concentration
Keywords:excess air, dissolved argon, groundwater, SF6 dating, Central Japan
Estimation of excess air component in groudwater sample is vital for precise groundwater dating using SF6. In this study, dissolved argon concentration was used for the estimation. We will report distriution of the excess air content in groudwater samples in central Japan, and discuss the impact for the SF6 dating.
