Production of [15O]water at low-energy proton cyclotrons.
نویسندگان
چکیده
We report a simple system for producing [15O]H2O from 15N in a nitrogen/hydrogen gas target with recycling of the target nitrogen, allowing production on low-energy proton-only accelerators with minimal consumption of isotopically enriched 15N. The radiolabeled water is separated from the target gas and radiolytically produced ammonia by temporary freezing in a small trap at -40 degrees C.

Direct simultaneous production of [15O]water and [13N]ammonia or [18F]fluoride ion by 26 MeV proton irradiation of a double chamber water target.
A simple double liquid chamber target was developed to provide the option for simultaneous production of [15O]H2O and either 13N or 18F using a single proton beam. Irradiation of natural water in a thin aluminium front chamber produced [15O]H2O by the 16O(p, pn)15O reaction directly. Large (0.5-1.0 Ci) doses of sterile [15O]H2O (greater than 99.95% radionuclide purity) were routinely prepared i...

Introduction: Nowadays, cancer is one of the most important concerns in human being's societies, more than one-third of people in around the world will get cancer during their lives. Physical dose depth distribution characteristic of protons in a tissue is determined with a low dose in the entrance region, maximum dose in the Bragg region, and rapid decline takes place near the...
متن کاملComparison of Copper-61 Radioisotop Production Yield via Reactions of 64Zn(p,α)61Cu, natZn(p,x)61Cu, 61Ni(p,n)61Cu, and natNi(p,x)61Cu in Hospital Cyclotron using TALYS, EMPIRE, and MCNPX Nuclear Codes
Background & Aims: Copper-61 (61Cu) is a radioisotope with a half-life of 3.33 hours which decays to nickel-61 isotope byβ+ emission (61%) or electron capture (39%). This radioisotope can be used in the evaluation of the blood supply of the heart and low-oxygen cancer tissues imaging with PET. 61Cu is mainly produced by bombarding zinc (Zn), nickel (Ni) and cobalt (Co) targets in medium cyclot...
