چکیده
Cross sections for (223,)(225)Ra, (225)Ac and (227)Th production by the proton bombardment of natural thorium targets were measured at proton energies below 200 MeV. Our measurements are in good agreement with previously published data and offer a complete excitation function for (223,)(225)Ra in the energy range above 90 MeV. Comparison of theoretical predictions with the experimental data shows reasonable-to-good agreement. Results indicate that accelerator-based production of (225)Ac and (223)Ra below 200 MeV is a viable production method.

225Ac and 223Ra production via 800 MeV proton irradiation of natural thorium targets.
Cross sections for the formation of (225,227)Ac, (223,225)Ra, and (227)Th via the proton bombardment of natural thorium targets were measured at a nominal proton energy of 800 MeV. No earlier experimental cross section data for the production of (223,225)Ra, (227)Ac and (227)Th by this method were found in the literature. A comparison of theoretical predictions with the experimental data shows ...
متن کاملCompare charged and uncharged particles leakage of plasma focus for medical radioisotopes production
In this study, to calculate the radioactivity of radioisotopes such as 11C, 15O, 18F and 123,124I in a focus plasma device for the production of medical radioisotopes, the particles of neutrons and protons with cubic targets of Nitrogen, Xenon, Carbon and a solid natural Boron is used. Particles energy are at the input of the program from 1MeV to 10MeV. Also, the total yield coefficient is cons...
متن کاملQuasi-free π Photoproduction from the Bound Nucleon
Differential cross-sections for quasi-free π photoproduction from the proton and neutron bound in the deuteron have been measured for Eγ = 200 − 400 MeV at θ lab γ = 136.2 ◦ using the Glasgow photon tagger at MAMI, the Mainz 48 cm Ø × 64 cm NaI(Tl) photon detector and the Göttingen SENECA recoil detector. For the proton measurements made with both liquid deuterium and liquid hydrogen targets al...
متن کاملStatistical uncertainty estimation in the calculation of the proton range in water phantom.
Introduction: GATE (Geant4 Application for Tomographic Emission) is a Monte Carlo simulation platform developed by the OpenGATE collaboration since 2001 and first publicly released in 2004. In Geant4, each physics process is described by a model (several models are sometimes available for a given physics process) and a corresponding cross-section table. All Geant4 physics model...

Background: The present study aimed to investigate the equivalent dose in vital organs, including heart and lung, due to secondary particles produced during breast proton therapy. Materials and Methods: The numerical ORNL female-phantom was improved and simulated using the Monte Carlo MCNPX code. The depth-dose profile of proton beams with different energies was simulated. The proper energy ran...
