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 (T1/2 = 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.
