Popocatepetl volcano is a high-risk active volcano in Central Mexico where the highest population density in the country is settled. Radon in the soil and groundwater together with water chemistry fr...
Radon activity in the atmosphere and its behavior in the environment have been investigated using LR-115 nuclear track detector. The complex geological structure of Wzgórza Niemczansko-Strzelinskie (...
Radon-in-soil monitoring at the Poas volcano (Costa Rica) has been performed together with water chemistry from the hot crater lake since 1981 and 1983 respectively. The results are discussed as a fu...
In the magmatic area of Sudetes covering the Karkonosze granite and adjacent volcano-sedimentary Intrasudetic Basin a study of atmospheric radon activity was performed by means of SSNTD Kodak LR-115....
本文在对比常规抛物线Radon变换、最小二乘抛物线Radon变换和高分辨率抛物线Radon变换的保幅性的基础上,重点分析了影响高分辨率抛物线Radon变换去噪方法保幅性的各种因素,认为对于最小二乘Radon变换和高分辨率Radon变换而言,信号在变换域中的分辨率都依赖于信号模型的“标准同相轴”假设,地震数据处理中各种实际因素导致信号同相轴偏离该假设,进而导致分辨率降低,影响Radon变换去噪方法的...
Radon activity concentrations measurements in some Jurassic caves of Poland are presented. The aim is to estimate the radiation doses to casual visitors, cavers and guides in show caves. Radon levels...
Atmospheric radon concentrations were monitored from autumn 2004 to winter 2007 in an abandoned coal mining area of SW Poland that contained various bedrock uranium contents, ranging from 1 to 8 ppm....
Rn (radon) is the major radioactive gas in volcanic area. The study of radon concentration variations in volcanic areas has been considered as a useful tool to investigate the volcanic activity in on...
Preface "IGCP Project 571: Radon, Health and Natural Hazards".
The present research is aimed at accessing the relationship between variation in the soil gases radon (222Rn) and helium (4He) and recently developed fissures and other neotectonic features in Nurpur ...
