Abstract

Environmental terrestrial gamma radiations (TGR) were measured in Pahang state Malaysia between January and April 2013. The TGR dose rates ranged from 26 to 750 nGy h−1. The measurements were done based on geology and soil types of the area. The mean TGR dose rate was found to be 176 ± 5 nGy h−1. Few areas of relatively enhanced activity were located in Raub, Temerloh, Bentong and Rompin districts. These areas have external gamma dose rates of between 500 and 750 nGy h−1. An Isodose map of the state was produced using ArcGIS9 software version 9.3. To evaluate the radiological hazard due to terrestrial gamma dose, the annual effective dose equivalent and the mean population weighted dose rate were calculated and found to be 0.22 mSv year−1 and 168 nGy h−1 respectively.This project is funded by the Atomic Energy Licensing Board (AELB) of Malaysia. Under grant title: Kajian Pemetaam Isodose 2013. This project also used various facilities provided by Universiti Teknologi Malaysia (UTM). The authors would also like to thank Mr. Joseph Yong for his hard work and endurance during the survey.
