• evaluate the accuracy of the calculation methods used in NEA Member countries for predicting long-term radiation doses to reactor pressure vessels and internal structures; • identify points for improvement and validate the performance of improved methods for fluence calculations; • initiate a study on the modelling of radiation-induced damage in metals. This report fulfils the first and secon...

This monograph comprises a set of notes which was developed to accompany a seminar series on the Concepts of Radiation Dosimetry given by the authors at Stanford University during the Spring Quarter 1970. It discusses the basic information required to understand the principles of photon and charged particle dose measurement from basic particle interactions to cavity chamber theory. As health ph...

Optimal management of cavernous sinus hemangiomas remains unclear. Total microsurgical removal of these neoplasms may be extremely difficult due to their rich vascularization. Three cases of cavernous sinus hemangioma treated with low-dose Gamma Knife radiosurgery are presented. Marginal dose varied from 10 to 13 Gy. Treatment planning and radiation dosimetry were done with a goal of conformal ...

131I-TM-601 is a 36-amino acid peptide, called chlorotoxin (TM-601), derived from scorpion venom labeled with I-131. TM-601 binds a receptor on the surface of tumor cells, and not on normal cells. A single dose of 131I-TM-601 administered intracranially to human xenografted mouse models of glioma has been shown to extend survival up to 269% in multiple studies. 131I-TM-601 is in a multi-center ...

background; environmental gamma ray refers to the gamma radiation from terrestrial sources and building materials. in enclosed spaces radiation can become a health hazard leading to potential increase in the rates of lung cancer. the goal of this study is to assess the exposure to natural gamma radiation of children in the schools of zanjan province. method; the natural gamma radiation was asse...

Background: Lymphocyte-dicentric assay is the most generally accepted method for biological dosimetry of overexposed individuals. In this study, the frequency of unstable chromosome aberration in blood lymphocytes was used to estimate radiation dose received by individuals. Evaluation of dose using a calibration curve produced elsewhere may have a significant uncertainty therefore, experiments ...

INTRODUCTION The increasing use of radiation sources of high activity for industrial and medical applications and in the generation of electric energy and the consequent increase in the probability of to occur accidents, becomes important the research and the development of detectors and dosimetry methods for quality control of the applied doses. The radiation dosimetry is important for all rad...

BACKGROUND AND OBJECTIVE Professional radiation workers are occupationally exposed to long-term low levels of ionizing radiation. Occupational health hazards from radiation exposure, in a large occupational segment of the population, are of special concern. Biological dosimetry can be performed in addition to physical dosimetry with the aim of individual dose assessment and biological effects. ...
