| Summary |
"In December of 1947 Mr. Robert Van Nostrand and the writer became interested in the problem of the distribution of natural radioactivity and the applications of radioactivity to geology. A cooperative survey of the literature on the subject was undertaken. Later the writer decided to follow up the survey with a research project. Consultations with Dr. Z. V. Harvalik of the Missouri School of Mines Physics Department, and Dr. E. L. Clark and Mr. O. M. Bishop of the Missouri Geological Survey, followed. The nature of the project was evolved when Dr. Clark, with the consent of the U. S. Bureau of Mines, offered to loan the writer the igneous section of the Bourbon, Missouri, well core. The equipment was designed and built, samples prepared and measurements taken during the summer months, June through September, 1948"--Preface, leaf iii. |
