Abstract

The limited number of radionuclides emitting alpha-particles and their limited availability is discussed. A new alpha-emitter ²³⁰U (T _1/2 = 20.8 d, 100% α) is suggested and its preparation from thorium target bombarded by accelerated protons (via initial formation of ²³⁰Pa (T_1/2 = 17.4 d, 8.4% decay to ²³⁰U)), or ⁴He is discussed. The Empire II model was used to calculate the excitation functions for the different products from bombardment of Th by protons. The calculated thick target yield for ²³⁰Pa is 0.6 mCi/μA·h, leading to about 24 μCi/μA·h of ²³⁰U or about 150 μCi/μA·h in the case of alpha-bombardment.
