Community-acquired Legionnaires’ Disease in a Newly Constructed Apartment Building
OBJECTIVES Legionnaires' disease (LD) is a severe type of pneumonia caused by inhalation of aerosols contaminated with Legionella. On September 22, 2016, a single case of LD was reported from a newly built apartment building in Gyeonggi province. This article describes an epidemiologic investigation of LD and identification of the possible source of infection. METHODS To identify the source o...
متن کاملRn- 222 Concentration and Gamma Dose Rate Measurements in the Vicinity of Hot Springs in Kerman Province, Southeastern, Iran.
Introduction: Radon-222 gas is a radioactive, colorless and odorless element that can cause lung cancer and stomach in humans with alpha-ray emissions. An important source of Radon-222 is the output water in springs, especially hot springs to emit ionision radiation. In this study, Rn-222 activity concentration and gamma dose rate levels in water sample of some selected hot spr...
متن کاملMEASUREMENT OF 222 Rn BY ABSORPTION IN POLYCARBONATES – RESEARCH AND PRACTICE
In the last few years, we have gathered experience in measurement of 222 Rn in air, water and soil-gas by absorption in polycarbonates. The method employs the remarkable absorption ability to noble gases of some polycarbonates, like Makrolon ® (the basic constructive material of CDs/DVDs). This report summarizes the key results of research and practical applications of this method. Calibration ...
