Abstract: Reconnaissance airborne radiometric survey of Qatar Peninsula revealed a number of radioactive features. Ground geologic and radiometric investigations led to the localization of some twenty anomalies having radioactive intensities ranging from 21 cps up to 615 cps, while the background radioactivity varies between 8 and 18 cps.<br>This paper deals with a statistical analysis of 1994 readings of field measurements of gamma radioac-tivity<br>of the various lithologies at the twenty anomalous localities. It has been found that these radioactive<br>anomalies are associated mainly with four different lithologies namely: sabkha deposits, depression silts,<br>wadi (alluvial) deposits and Lower Dam marly limestones.<br>Geostatistically, the recorded radioactive anomalies in Qatar Peninsula can be grouped into two main<br>types. The first and more significant type is characterized by a sharp peak, and it comprises most of the<br>anomalies in sabkha deposits. The second type displays a broad anomalous zone, and it includes all other<br>anomalies which represent lithologic anomalies due to the relatively higher natural radioactivity of their<br>host materials with respect to the surroundings.
