Cosmetics play an important role of human external appearance, its products used to alter or enhance the facial appearance or the body and skincare, currently worldwide consumed with frequently use increasing the human body exposure to the various chemica... see more

Indoor radon concentrations were measured in dwellings of the earthquake-affected areas of Kathmandu valley, Gorkha, and Sindhupalchowk districts of Nepal using passive radon dosimeter LR115, a Solid State Nuclear Track Detector, SSNTD. The radon concentr... see more

The city of Lima, capital of Peru, has about 11 million inhabitants. Lima has no records about the indoor Radon 222 concentration levels in dwellings. Hereby, we are planning to register the indoor radon concentrations in Lima and in other cities of Peru ... see more

Analytic calculations and Monte Carlo simulations of track distributions induced by radon and its alpha emitter daughters, for different chamber geometries and critical incidence angles, were carried out. It was assumed uniform distribution of 222Rn and i... see more

Este artigo analisa o desempenho de detectores com múltiplas antenas transmissoras e múltiplas antenas receptoras (MIMO – multiple-input multiple-output) em canais com desvanecimento correlacionados. Dois esquemas de detecção MIMO denominados erro quadrát... see more

Thermal neutron flux (?th) of Americium-Beryllium (Am-Be) neutron source has been measured by adopting the foil activation method. The neutrons emitted from Am-Be source are used to activate the indium-115 (115In) foil. The gamma radiations emitted from t... see more

El vínculo entre la prolongada exposición al radón y el riesgo de incidencia de cáncer de pulmón o estomacal, hace de la labor de ubicar las zonas con altos niveles de radón, un aspecto importante en la salud pública. Una de las principales fuente del rad... see more

This study develops a gas chromatographic method coupled to micro-electron capture detector to determine four basic polychlorinated dibenzo-p-dioxins (PCDDs) congeners: 1, 1,2,3,7,8-pentachlorodibenzo-p-dioxin; 2, 2,3,7,8-tetrachlorodibenzo-p-dioxin; 3, 1... see more
