[ 1 ] - Assessment of in vitro radiosensitivity parameters of breast cancer cells following exposure to radiotherapy hospital-based facilities
Introduction: The aim of the present study was to assess the radiosensitivity parameters for SK-BR-3 (SKBR3) breast cancer cells that could be implemented in the cutting-edge treatment planning systems (TPS) for accelerated partial-breast irradiation (APBI). Materials and Methods: The cell survival fraction and its relevant radiosensitivity coefficients, namely α and β, in linear-quadratic (LQ)...
[ 2 ] - A Monte Carlo Study for Photoneutron Dose Estimations around the High-Energy Linacs
Background: High-energy linear accelerator (linac) is a valuable tool and the most commonly device for external beam radiation treatments in cancer patients. In the linac head, high-energy photons with energies above the threshold of interaction produce photoneutrons. These photoneutrons deliver the extra dose to the patients in the planning treatment and increase the risk of secondary cancer.O...
[ 3 ] - Internal dosimetry of radioiodine using ICRP reference phantoms and updated biokinetic model
The purpose of this study is to estimate internal dose to human body due to administration of I-131 using new biokinetic model of iodine. In this respect, we used international commission on radiological protection (ICRP) adult reference phantoms. Monte Carlo calculations were performed using MCNPX 2.6 code. The average dose to target organ per disintegration inside source organ, namely S facto...
