Available in PDF, EPUB and Kindle. Book excerpt: Airborne gamma-ray data from Malawi, Africa were used to develop an automated system for computing on-line atmospheric background radioactivity. The atmospheric backgrounds were calculated using lead-shielded upward-looking detectors calibrated from airborne measurements over a large lake and areas with varying proportions of uranium and thorium. The method was tested by producing atmospheric uranium background maps and background corrected uranium count rate maps from two different areas.
