“…63 While no identifying name or version of this code was declared, the MC code used by the University of Athens group has been well-validated under a variety of circumstances appropriate for radiation transport calculations for brachytherapy sources. Photoatomic interaction cross-sections from Scofield, 64 Hubbell et al, 65 and Hubbell and Øverbø 66 were used. The MC code uses NIST XCOM mass-energy absorption coefficients from Hubbell and Seltzer, 56 and atomic data from Plechaty et al 67 were used for characteristic x-ray generation.…”

Cs (IsoRay Medical model CS-1 Rev2). Observations are included on the behavior of these dosimetry parameters as a function of radionuclide. Recommendations are presented on the selection of dosimetry parameters, such as from societal reports issuing consensus datasets (e.g., TG-43U1, AAPM Report #229), the joint AAPM/IROC Houston Registry, the GEC-ESTRO website, the Carleton University website, and those included in software releases from vendors of treatment planning systems. Aspects such as timeliness, maintenance, and rigor of these resources are discussed.Links to reference data are provided for radionuclides (radiation spectra and half-lives) and dose scoring materials (compositions and mass densities). The recent literature is examined on photon energy response corrections for thermoluminescent dosimetry of low-energy photon-emitting brachytherapy sources. Depending upon the dosimetry parameters currently used by individual physicists, use of these recommended consensus datasets may result in changes to patient dose calculations. These changes must be carefully evaluated and reviewed with the radiation oncologist prior to their implementation.

In this paper the Sn loss from thin films of the material system Cu-Zn-Sn-S and the subsystems Cu-Sn-S and Sn-S in high vacuum is investigated. A combination of in situ x-ray diffractometry and x-ray fluorescence ͑XRF͒ at a synchrotron light source allowed identifying phases, which tend to decompose and evaporate a Sn-containing compound. On the basis of the XRF results a quantification of the Sn loss from the films during annealing experiments is presented. It can be shown that the evaporation rate from the different phases decreases according to the order SnS → Cu 2 SnS 3 → Cu 4 SnS 4 → Cu 2 ZnSnS 4 . The phase SnS is assigned as the evaporating compound. The influence of an additional inert gas component on the Sn loss and on the formation of Cu 2 ZnSnS 4 thin films is discussed.

For the purpose of avoiding the radiation blistering of the lithium target for neutron production in BNCT (Boron Neutron Capture Therapy) device, trilaminar Li target, of which palladium thin layer was inserted between cupper substrate and Li layer, was newly designed. The Li/Pd/ Cu trilaminar structures of the synthesized target were characterized under 3 keV H 2 + irradiation by XPS and XAFS technique, which provides structural/electronic properties of solids, and information about the local structure, such as the nature and number of surrounding atoms and inter-atomic distances. The following conclusions were derived; PdCu physical bonding was produced between the Pd and Cu interface by electro-less plating Pd deposition on a high purity Cu plate. From the XAFS observation of white line of Pd, the Pd L 3 edge jump was found after H 2 + irradiation, this fact indicates increase of hole density in Pd 4d-band. 0.9 eV chemical shift was also observed in Pd L 3 white line for monolayer and 1 µm Pd/Cu samples, which will affect the quality of the Li/Pd/Cu target due to the formation of PdH x in palladium insert layer.
