THE MAGNESIUM-28-ALUMINUM-28 SYSTEM: AN ALUMINUM-28 GENERATOR [PDF]

open access: yesThe International Journal of Applied Radiation and Isotopes, 1963
A milking method was developed for the production of the short-lived Al/ sup 28/ for use in physiological experiments. A Mg/sup 28/ solution is obtained by the irradiation and purification of a Li/sup 6/Mg/sup 26/ alloy, and it is placed on a Dowex 50W column in the Na/sup +/ form and then washed with 1 N NaOH.
