This study summarizes the 20-year efforts for dose reconstruction in tooth enamel of the Techa riverside residents exposed to ionizing radiation as a result of radionuclide releases into the river in 1949-1956. It represents the first combined analysis of all the data available on EPR dosimetry with teeth of permanent residents of the Techa riverside territory. Results of electron paramagnetic ...

Knowing patient exact dose during radiological activities is considered as one of the main principles to decrease radiation-induced dangers which are not really necessary and affect a great deal of people. In this respect, in recent years many extensive studies have been done on types of photodiodes and production of X-ray detectors using semiconductor elements. Since these elements are not ver...

Background: Reliable estimation of radiation-absorbed dose is necessary to evaluate the benefits and the risks of radiopharmaceuticals used for diagnostic or therapeutic purposes in nuclear medicine. Materiel and Methods: This study included 47 patients treated with iodine-131 for Graves’ disease. A comparative study between Geant4 Monte Carlo simulation and MIRD formalism was carried out to ev...

At the International Atomic Energy Agency Symposium on "National and International Standardization of Radiation Dosimetry" held in Atlanta during 5 -9 December 1977, it became quile evident that the institutions in the IAEA/WHO network of Secondary Standards Dosimetry Laboratories (SSDLs) have become recognized as having a necessary and well-defined objective. The link they have established wit...

students derive much benefit from a book of this type. As a supplement to their standard texts it not only aids them in understanding structure but stimulates their studying of anatomy by integrating physiology and emphasizing the practical application of such knowledge. A book of this type allows a busy physician to review in a short time the essentials of normal anatomy of various structures ...

This article aims at presenting in a didactic way, dosimetry concepts and methods that are relevant for radio-embolization of the liver with 90 Y-microspheres. The application medical internal radiation dose formalism to is introduced. enables simplified dosimetry, where absorbed given tissue depends on only its mass initial activity. applied single-compartment method, partition model, liver, t...

Biological dosimetry, that is the estimation of the dose of an exposure to ionizing radiation by a biological parameter, is a very important tool in cases of radiation accidents. The score of dicentric chromosomes, considered to be the most accurate method for biological dosimetry, for low LET radiation and up to 5 Gy, fits very well to a linear-quadratic model of dose-effect curve assuming the...
