High-energy proton induced reactions for the production of fluorine-18
Description
Fluorine-18 is a positron-emitting radionuclide of great interest in the applications of computer assisted positron-emission tomography. The production of 18F via proton induced reactions on a series of low-Z targets was studied. External beams of protons of 67.5 MeV were used to bombard Na, Mg, and Al targets and the resulting 18F-induced radioactivities were measured using gamma-ray spectrometry. Cross sections (mbarn) and yields (mCi/μAh) were then calculated in the 67.5- to 20MeV energy range. Thick-target 18Fe yields were measured as 88 +/-12 mCi/μAh for Na (67-21 MeV) targets; 26 +/- 3.5 mCi/μAh for Mg (67-25 MeV) targets; and 23 +/- 3 mCi/μAh for Al (67-22 MeV) targets. These methods are also compared on the basis of experimental results and using theoretically-predicted cross sections from a modified ALICE 82 (named ALISO) code. Finally, the potential of these methods for the large-scale production of 18F is also discussed. (author). 26 refs, 5 figs, 5 tabs
