External dose reconstruction in tooth enamel of Techa riverside residents.
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 ...
متن کاملTecha River Dosimetry System: Current Status and the Future
The Techa River Dosimetry System (TRDS) has been developed to provide estimates of external and internal doses for residents living on the Techa River, which was contaminated as a result of radioactive releases in 1949–1956. This system represents a modular database processor that uses, depending on the input data for an individual, various elements of several databases (or modules). Large amou...
متن کاملAssessment Of Tooth Tissues Dose Rate Coefficients From Incorporated Strontium-90 In EPR Dose Reconstruction For The Techa Riverside Population
The method of electron paramagnetic resonance (EPR) in the tooth tissues is used to reconstruct cumulative absorbed dose for the Techa River residents. The interpretation of EPR-measurements presents a difficult task due to a contribution of external and internal exposure. It is very important to assess the real contribution of Sr incorporated in tooth tissues to the total EPR dose. For this pu...
متن کاملRetrospective dosimetry using fingernail in nuclear industries: A review paper
Generally, doses greater than 2Gy can produce acute biological effects in humans. For this reason, to measure and record the cumulative dose, especially in radiation users, the need for a personal dosimeter has been strongly felt by the researchers. The purpose of this study is to introduce retrospective dosimetric techniques, in particular the use of nails as a natural tool for determining cum...
متن کاملEvaluation of Effective Sources in Uncertainty Measurements of Personal Dosimetry by a Harshaw TLD System
Background: The accurate results of the individual doses in personal dosimety which are reported by the service providers in personal dosimetry are very important. There are national / international criteria for acceptable dosimetry system performance.Objective: In this research, the sources of uncertainties are identified, measured and calculated in a personal dosimetry system by TLD.Method: T...
