Dose-rate Conversion Factors for External Exposure to Photons and Electrons

External Dose Conversion Factors from Finite Airborne Radioactive Plumes

Absorbed dose rate conversion coefficients for reference terrestrial biota for external photon and internal exposures.

The paper describes dosimetric models that allow the estimation of average radiation exposures to terrestrial biota due to environmental sources in the soil as well as internal uniform distributions of radionuclides. Simple three-dimensional phantoms for 13 faunal reference organisms are specified. The calculation of absorbed dose per unit source strength for these targets is based on photon an...

Time to Sputum Smear Conversion in Smear-Positive Pulmonary Tuberculosis Patients and Factors for Delayed Conversion

Pulmonary tuberculosis is a common infection worldwide. In the eastern part of Iran, fluctuations in tuberculosis prevalence are seen due to the migration of people from Afghanistan. The aim of this study was to evaluate the time of bacteriologic sputum conversion after treatment and affecting factors in those whose smear does not become negative.This study was carried out on 85 smear-positive ...

Assessment 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...
