Maps of four quadrants in the Galveston area surveyed as part of a radiological survey, outlining "Radioactivity levels in hundreds of counts per second normalized to 500 ft above ground." Scale 1:250,000.

Report describing an Aerial Radiological Measuring Survey (ARMS) of the Galveston Area between Jan. 27 and Feb. 17, 1962. The survey was part of a nationwide program to measure present environmental levels of gamma radiation. Aerial measurements of ground radioactivity were consistent everywhere with what was expected considering the geology of the area.
