Geophysical applications of radon measurements


Holzman, Benjamin (1933) Geophysical applications of radon measurements. Master's thesis, California Institute of Technology.


In recent literature statements to the effect that a fault will be evidenced by a higher radon concentration in the overlying soil, that the radon content of soil is an oil bearing region is higher, and that soil formations appear to have more or less characteristic radon contents, have appeared. Since radioactive measurements are concerned with extremely small quantities of the order of 10^(-12) grams of radium per gram of rock, a study of the methods of standardization for radon apparatus is presented in an attempt to indicate the requirements for accurate and precise measurements. The use of a standard radium solution, uranium minerals, and the Duane and Laborde formula are considered. An analysis of the theory underlying the geophysical applications suggested above indicates that soil formations are not expected to have a more or less characteristic radon content, that a high radon concentration in the overlying soil of an oil bearing region cannot be correlated genetically with the oil, and that it is possible to have a high radon concentration at a fault. A simplified technique for the measurement of radon in solutions adaptable to field work is demonstrated. Surveys of the radon concentration of underground waters of Pasadena, indicated no systematic increase towards the Raymond Fault.
