The Contribution Due to Cs-130 was Later O059300900017 Subtracted When It had Been Obtained by Positron O059300900018 Measurements.

In One Irradiation,For Example,the TargetO059301000006 Was Dissolved As Soon As Possible After the End of O059301000007 Irradiation and in the Second an Interval of About 1- O059301000008 Hour was Allowed to Elapse Before Dissolution.
