Atomic nuclei display various exciting phenomena depending on their location along the nuclear chart and values of other parameters such as angular momentum, excitation energy, isospin etc. One such location is the 100 £ A £ 110 mass region, which has generated considerable research interest since last two decades. The nuclei in this region exhibit admixture of single particle and collective ex...

AIM The aim of this study is to quantify the influence of the photon energy spectrum of brachytherapy sources on task group No. 43 (TG-43) dosimetric parameters. BACKGROUND Different photon spectra are used for a specific radionuclide in Monte Carlo simulations of brachytherapy sources. MATERIALS AND METHODS MCNPX code was used to simulate 125I, 103Pd, 169Yb, and 192Ir brachytherapy sources...

Radioisotopes used in medical practice and for industrial or research applications are often produced with charged particle induced reactions. Although mostly proton beams are used, the cross sections of deuteron induced reactions are sometimes higher and lead to higher thick target production rates. For 13 targets, ranging from mass 61 to 176, an experimental comparison between cross sections ...

Recently, to eliminate problems associated with seed type sources, RadioMed Corporation (Tyngsboro, MA) introduced RadioCoil 103Pd sources for interstitial prostate implants. The RadioCoil sources are available in integral lengths ranging from 1.0 cm to 6.0 cm. In this project, dosimetric characteristics of these sources were determined following the TG-43U1 recommendations, with consideration ...

introduction: clinical application of encapsulated radioactive brachytherapy sources has a major role in cancer treatment. in the present research, the effects of different tissue densities on the dose distribution of a 103pd brachytherapy source in a spherical phantom of 50 cm radius have been studied. material and methods: as is well known, absorbed dose in tissue depends to its density, but ...
