Abstract: Fully processed gamma ray data may be displayed by a variety of methods that can interpret profiles and radioelement networks. After the 1990s, advances in gamma ray spectrometry data, regarding image processing techniques have been useful. However, traditional mapping methods like profiles and contour maps have their own advantages and are still being used today. Although, some visualization techniques can be considered in order to display the updated gamma ray spectroscopy data, but none of the those methods, alone, are not being used for mapping and the appropriate interpretation and they should be combined with other methods. Graphical representation of airborne gamma ray spectrometry data along with developing low-cost processing systems has gained tremendous popularity. Image format enables the interpreter to benefit from a variety of digital image processing techniques, including image enhancement and extracting special shapes. In this paper, we have used different techniques of visualizing digital as well as different color spaces. Acquired radiometric data of elements such as potassium, uranium and thorium in Islamabad district were converted to color images using Geosoft software and then, ternary radioelement map of this region provided in RGB color space. Finally, we processed the images, extracted significant shapes, identified hot areas of uranium anomalies, and suggested promising indices of radioactive mineral deposits for the exploratory procedures.
