Relation 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 کاملEstimation of neutron effective dose from DD and DT neutron generators and the design of appropriate shield for standing user
Neutron Generators (NG) are used as a neutron source for different applications. During recent years, major efforts are underway to develop a high yield compact NG. In this way, radiation protection aspects need to be considered during the operation of these high yield NGs. In this paper the neutron effective dose of a NG operator has been calculated using MCNPX Monte Carlo code. The results sh...
متن کاملAssessment of the External Exposure Dose to Humans From
At present the Baltic Sea is considered to be the most contaminated with anthropogenic radionuclides in comparison to any other part of the World Ocean. Anthropogenic radionuclides (mainly 137 Cs and 90 Sr) found in the seawater are sources of the external exposure that contributes to the total radiation exposure to humans. The variations of activity concentrations of 137 Cs and 90 Sr in the wa...
متن کاملNeutron Contamination Unexpected Dose in Varian LINAC
Introduction: Neutron contamination is very harmful for the patients receiving radiation therapy due to the high relative biological effect of neutrons. Medical linear accelerators head are made up of materials with high atomic numbers, and High-energy photons interaction with heavy materials can produce neutron contamination. In this study, neutron equivalent dose, neutron spe...
متن کاملAssessment of Effective Dose Equivalent from Internal Exposure to 222Rn in Ramsar City
Introduction In this study, effective dose equivalent for the public due to internal exposure to 222radon (222Rn) was evaluated in three regions of Ramsar, a northern coastal city in Iran. Materials and Methods Measurements were carried out using a radon monitoring device. Outdoor and indoor radon concentrations were measured within 24 hours with an integration in...
