Myocardial infarction and occupational exposure to particles from various sources

Risk Assessment of Occupational Exposure to Cement Respirable Particles and Crystalline Silica in a Cement Factory

Introduction: Cement factory workers exposure to airborne particles containing crystalline silica in Portland cement chemical compound can caused pulmonary diseases, including silicosis and lung cancer. The aim of this study was to assess the risk of occupational exposure to respirable cement dust and crystalline silica in a cement factory in Khorasan Razavi province. Methods: In this cross-se...

Exposure of school children to alpha particles

Background: A substantial part of the public’s natural radiation dose is due to the inhalation of radon gas. Most of the exposure occurs indoors where the airborne concentration of radon and its decay products is usually higher than outdoors. Materials and Methods: Radon activity concentration has been measured twice in 50 classrooms in 5 levels (10 each) during summer and winter using solid-st...

Evaluation of Radiation Exposure Pattern and Radiation Absorbed Dose Resulting from Occupational Exposure of Anesthesiologists to Ionizing Radiation

Introduction: Little information is available concerning the radiation exposure of anesthesiologists, and no such data have previously been collected in Iran. This prospective study was performed to determine the amount of radiation exposure of anesthesiologists for the purpose of assessing whether or not dangerous levels of radiation exposures were being reached, and to identify factors that c...
