Dose-rate constant and air-kerma strength evaluation of a new 125I brachytherapy source using Monte Carlo

open access: yesBrazilian Journal of Radiation Sciences, 2021
Brachytherapy is a modality of radiotherapy which treats tumors using ionizing radiation with sources located close to the tumor. The sources can be produced from several radionuclides in various formats, such as Iodine‑125 seeds and Iridium‑192 wires ...

ESTIMATION OF ENTRANCE SURFACE AIR KERMA IN DIGITAL RADIOGRAPHIC EXAMINATIONS

open access: yesRadiation Protection Dosimetry, 2021
Abstract Purpose: Contribution of radiation doses from medical X-ray examination to collective dose is significant. Unusually, high doses may increase the risk of stochastic effects of radiations. Therefore, radiation dose assessment was performed in 241 digital X-ray examinations in the study and was compared with published dose ...

Comparison of the NIST and ENEA air kerma standards

open access: yesJournal of Research of the National Institute of Standards and Technology, 1998
A comparison was made between the National Institute of Standards and Technology (NIST) and Ente per le Nuove Tecnologie l'Energia e l'Ambiente (ENEA) air kerma standards for medium energy x rays and 60Co gamma rays. The comparison took place at ENEA in June 1994. Two different transfer chambers from NIST were used for the comparison.
