Production of 85Sr at a 18MeV-cyclotron and purification for geochemical investigations.

The production of (85)Sr by irradiation of a Rb-target at a cyclotron was investigated. The purification of the radionuclide was performed by a Sr-selective resin. (85)Sr was separated in no-carrier-added aqueous solution with a recovery of 98% and a concentration up to 6.6MBq in 200µl.
