Fetus dose calculation during proton therapy of pregnant phantoms using MCNPX and MCNP6.2 codes [PDF]

Radiation Measurements, 2021
Radiotherapy of pregnant cancer patients is not common, but when applied accurate assessment of the fetus dose is required, especially since the treatment planning systems are not able and do not allow accurate assessment of out-of-field doses.

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.
