ABSTRACT:
A mobile system comprising
of a Geiger-Muller (GM) dosimeter connected with a smart phone was used for
ambient gamma dose rate survey within the districts and on the roads within the
state of Kuwait. While the dosimeter provides data on gamma dose rates, the
smart phone provides the GPS navigation information and saves the data for
subsequent analysis and mapping. The survey covered a total distance of about
2300 km within the country and 3117 data points were recorded to show the dose
rate distribution on the map of Kuwait. The results show that the ambient dose
rates in Kuwait range from 40 to 180 nSv.h-1 with a mean value of
103 nSv.h-1. The dosimetric system described has good potential as a
tool for determining baseline background radiation dose rates in an area.
