Simulation of vanadium-48 production using MCNPX code [PDF]

Nuclear Technology and Radiation Protection, 2012
Vanadium-48 was produced through the irradiation of the natural titanium target via the natTi(p, xn)48V reaction. The titanium target was irradiated at 1 mA current and by a 21 MeV proton beam for 4 hours. In this paper, the activity of 48V, 43Sc, and

Evolution of dose distribution for a ¹²⁵I eye plaque using MCNPX and Plaque Simulator software. [PDF]

Precis Radiat Oncol
Abstract Objective Eye plaque radiation therapy is the treatment of choice for small‐ and medium‐sized choroidal melanomas. This study investigated the dose distribution around eye plaques containing 125I seeds to treat ocular melanoma using Monte Carlo N‐Particle eXtended (MCNPX) and Plaque Simulator (PS) software.
