Radon is the most important source of natural radiation to human beings and second major causative agent lung cancer other than smoking. In recent years, hazards exposure thoron (Rn-220), another isotope radon, its progeny have gained consensus. To accurately evaluate dose level Rn-220 progeny, a standard chamber with strong regulation ability for needs be established scale or calibration measu...

During the second haft of 1979, anomalously high emanation of radon was recorded at two stations of the automated radon-thoron monitoring network operated by the W. K. Kellogg Radiation Laboratory of the California Institute of Technology. The two stations exhibiting major anomalies, Kresge and Dalton Canyon, are located approximately 30 km apart on the frontal fault system of the Transverse Ra...

For a healthy indoor environment, it is important to understand which materials and factors favor the generation of high levels radon. A preliminary multivariate statistical analysis was carried out on two datasets concerning radon building in Campania Region using Principal Component Analysis (PCA) k-means partitional technique. total 13 parameters related were used. The results show greater c...
