Zakaria Saâdi,Nahla Mansouri,Laurent Marie et al.
Zakaria Saâdi et al.
In order to study effectiveness of soil radon mitigation systems in dwellings basements, it is necessary to develop robust numerical models that can estimate time-varying radon concentration in the basements. However, development of such mo...
Ecological half-life of radiocesium in white-tailed deer on the Department of Energy's Savannah River Site: What can a half century of field monitoring tell us? [0.03%]
美国能源部萨凡纳河サイト的白尾鹿体内的放射性铯生态半衰期：半个世纪的现场监测能告诉我们什么？

Karen F Gaines
This paper estimates the 137Cs ecological half-life of white-tailed deer inhabiting the Department of Energy's Savannah River Site (SRS) based on sex and age using data collected over a 51-year time-period. With a physical half-life of 30.2...
Detection of radioactivity of unknown origin: Protective actions based on inverse modelling [0.03%]
未知来源放射性的检测：基于逆向模型的防护行动
Jasper M Tomas,Valesca Peereboom,Astrid Kloosterman et al.
Jasper M Tomas et al.
The detection of radioactivity of unknown origin necessitates the use of models that can quantify unknown corresponding source term parameters. In this work, a method for solving this inverse problem is described. The main goal of the metho...
