Modeling the inhalation enhancement factor in prospective radiological risk assessment

A Prospective Radiological Risk Assessment for a Phosphate Industry Project

The Santa Quitéria Project is the major Brazilian uranium mine project, nowadays. A peculiarity of this project is the association of uranium with phosphate and the mining and processing of both by two different enterprises. A private company will be responsible for the production of phosphoric acid and a state owned company will be responsible for the production of yellow cake. At full capacit...

Radiological risk assessment of use of phosphate fertilizers in soil

ABSTRACT Background: The radiological impact of the use of phosphate fertilizers in soil is due to the internal irradiation of the lung by the alpha particles, short lived radon-thoron progeny and the external irradiation of the body by gamma rays emitted from radionuclides in situ. This paper describes the results of gamma spectrometric measurements of the concentration ...

A Prospective Study on QT Dispersion in Neonates: A New Risk Factor

Background: QT dispersion (QTd) especially after ischemic heart disease and myocardial infarction is a prognostic predictor of mortality, in adult medicine.  Objective: This study was undertaken to determine the correlation between QT dispersion and neonatal stress. Neonates were divided into 3 groups: normal term (30 cases), normal preterm (30 cases) and sick neonates (36 cases), born between ...
