The Monte Carlo Assessment of Photon Organ Doses from 222Rn Progeny in Adult ORNL Phantom
Introduction The potential hazards posed by exposure to radiation from radon have been of great concern worldwide, since it is especially associated with increased risk of lung cancer. Some radioisotopes of radon progeny deposited in the human lungs emit β particles followed by the γ rays. While γ rays are comparatively less damaging to the respiratory system than α and β particles, it is the p...
متن کاملRelation between Teeth-dose and Effective Dose for External Photon Exposure
INTRODUCTION Electron spin resonance (ESR) dosimetry using dental enamel is expected to be applicable to individual dose assessments, in the case where no dose information can be obtained from dosimeters, such as radiation accident. This method is based on the assumption of the linear relation between intensity of ESR signal induced by CO3 radicals and the absorbed dose in dental enamel. The ES...
متن کاملMeasurement of organ dose in abdomen-pelvis CT exam as a function of mA, KV and scanner type by Monte Carlo method .
Background: CT is a diagnostic imaging modality giving higher patient dose in comparison with other radiological procedures, so the calculation of organ dose in CT exams is very important. While methods to calculate the effective dose have been established (ICRP 26 and ICRP 60), they depend heavily on the ability to estimate the dose to radiosensitive organs from the CT procedure. However, dete...

متن کاملDevelopment of Computed Tomography Head and Body Phantom for Organ Dosimetry
Introduction: Quality assurance in Computed tomography (CT) centers in developing countries are largely hindered by the unavailability of CT phantoms. The development of a local CT phantom for the measurement of organ radiation absorbed dose is therefore requisite. Material and Methods: Local CT phantoms were designed to meet the standard criteria of 32 cm diameter for body, 16 cm diameter for...
