Results of the measurement of indoor radon and thoron carried out in and around Srirampura, Bangalore, India using passive detector technique is presented. Measurements were carried out using twin cup radon-thoron dosimeter using small strips of 12 micron thick LR-115 Type II nuclear track detectors. Measurements were carried out in 60 dwellings for a period of one year on a quarterly time inte...

Inhalation of indoor radon has been recognized as one of the health hazards. In the present work a set of indoor radon measurements was carried out, in different Egyptian houses in Alexandria city, built of the same type of building materials, using time–integrated passive radon dosimeters containing LR-115 Type II solid state nuclear track detector. Measurements were carried out from October 2...

Solid State Nuclear Track Detectors (SSNTD) are commonly used for long term measurements of radon, thoron and progeny concentrations. In the present study, we compared the optical counting method and the spark counting technique for counting the alpha tracks on LR 115 track detector films. The paper discusses the various parameters that are innate in the process. More than 300 films were counte...

Energy-dispersive X-ray fluorescence (EDXRF) spectrometry was previously proposed to measure the thickness of the cellulose nitrate layer of he commonly used LR 115 solid-state nuclear track detector (SSNTD). The present work is devoted to the investigation whether the X-ray radiation nvolved in EDXRF spectrometry will induce degradation of the cellulose nitrate. For this purpose, Fourier trans...

This study assesses the indoor radon and its progeny in some dwelling in Moradabad of Western Uttar Pradesh by using LR-115 plastic track detector. The measurements were made in 66 residential houses from January 2012 to December 2012 hanging twin cup radon dosimeter at a height of 1.5-2.0 m from ground level. The twin cup radon dosimeter can record the values of radon, and its decay products s...

In view of the fact that the radon progeny contribute the highest to the natural radiation dose to general populations, large scale and long-term measurements of radon and its progeny in the houses have been receiving considerable attention. Solid State Nuclear Track Detector (SSNTD) based systems, being the best suited for large scale passive monitoring, have been widely used for the radon gas...

El objetivo de la presente investigación fue medir las concentraciones radón en viviendas los distritos Provincia Lambayeque mediante detectores LR-115 Tipo II modo descubierto. Se utilizó trazas nucleares estado sólido (SSNTDs), películas nitrato celulosa LR 115 tipo II. número se determinó por distrito considerando densidad poblacional y tratando cubrir tanto zona urbana como rural. Los fuero...

The (CR–LR) difference technique, based on the CR-39 and LR 115 detectors, for the determination of implanted Po in glass after deposition of short-lived radon progeny, was analyzed in details in this paper. The sensitivities of both detectors were calculated using the Monte Carlo method with V functions particularly derived in our previous works for the detectors used in the present experiment...

The lipid content and fatty acid (FA) profile in pig tissues are strongly influenced by genotype and nutrient supply, with implications in meat quality. The de novo lipid synthesis and pattern of FA unsaturation could be an important cause of variation in the overall efficiency of energy utilization among breeds. To test the effects of pig genotype and CP supply on the evolution of back-fat tis...
