| Summary: | World over there have been isolated cases of reported radiation emergencies, occurring at a very small probability. Environmental radiation mapping of vast area using mobile platforms is one of the methodologies used for quick radiological assessment. The utilization of several portable radiation monitoring instruments for mapping an area and the techniques developed are described. Design aspects of mobile monitoring vehicle for appropriate positioning of detectors and the speed of vehicle are optimized. The mobile radiological monitoring of cities help in quickly generating baseline data and data of a city is given in this paper. The utility of gamma spectrometer in a mobile monitoring vehicle are dealt in detail. The paper discusses various aspects of mobile monitoring, methodology, its application and representation on geographical information system under different situations.
