Photonuclear production of Ca for Ca/Sc generator from natural CaCO targets.

This work investigated the indirect production of Sc from natural Ca targets via Ca(γ,n)Ca→Sc + β + ν‾ with incident electron energies of 30, 35, and 40 MeV. The Ca production yields were simulated using the PHITS Monte Carlo simulation code and compared to experimental data. The simulated production rates for all three irradiations are in good agreement with experimental data within uncertainties.

Imaging and dosimetric characteristics of Cu.

In recent years the use of beta-emitting radiopharmaceuticals for cancer therapy has expanded rapidly following development of therapeutics for neuroendocrine tumors, prostate cancer, and other oncologic malignancies. One emerging beta-emitting radioisotope of interest for therapy is Cu (t: 2.6 d) due to its chemical equivalency with the widely-established positron-emitting isotope Cu (t: 12.
