This paper presents a systematic study of the dose response characteristics of two new models and one commonly used model of GAFCHROMIC film: HS, XR-T, and MD55-2, respectively. We irradiated these film models with three different radiation sources:

Purpose: Trains of multiple 192 Ir seeds are used in many clinical trials for intravascular brachytherapy. 192 Ir source is commonly considered as a gamma emitter, despite the understanding that this radionuclide also emits a wide range of electron a

The dose distributions around two different arrangements of a single radioactive 192 Ir seed in water, (1) with air channels at the ends, and (2) surrounded by two nonactive (“dummy”) seeds on both longitudinal ends, were calculated using MCNP4CM
