Simple Method for Producing ¹³NN and ¹⁵OO by Proton Bombardment of Aqueous Phase

Abstract

A simple method has been developed for the production of ¹³NN and ¹⁵OO by proton irradiation of aqueous solutions. 90 mCi of ¹³NN was obtained in a 200 ml of He by using 1.0M NH₄Cl solution at pH 11 as the target with 10 min irradiation of 15 MeV, 10 μA protons. 80 mCi/min of ¹⁵OO was continuously obtained in a 200 ml of O₂ by using pure water as the target with 40 MeV, 2μA protons. The radiochemical purity of these short-lived radioactive gases obtained by this method was >99.9% by passing through a single absorber.
