Groundwater dating by estimation of groundwater flow velocity and dissolved 4He accumulation rate calibrated by 36Cl in the Great Artesian Basin, Australia (2009)

Mahara, Yasunori, Habermehl, M.A., Hasegawa, T., Nakata, K., Ransley, T.R, Hatano, T., ...

We tested two methods for dating groundwaters that cannot be reliably measured by 36Cl dating alone, one based on groundwater flow velocity plus distance along a flow path and the other based on 4He...

Separation of dissolved Kr from a water sample by means of a hollow fiber membrane (2009)

Ohta, Tomoko, Mahara, Yasunori, Momoshima, N, Inoue, F., Shimada, J., Ikawa, R., ...

We investigated extraction of the krypton (Kr) radioisotope 85Kr from groundwater having an ultra-low concentration with a Kr extraction system using an external inflow type hollow fiber membrane....
