Abstract

Dose mapping is one of the methods used to identify the dose distribution in any radiation facility. This study aims to visualise dose distribution at Long Term Storage Facility (LTSF), Bukit Kledang using thermoluminenscene dosimeter (TLD) by Geographical Information System (GIS). A total of 50 point were identified at LTSF for dose mapping using passive measurement, thermoluminescence dosimeter (TLD). TLD chips undergo anneal process before using, installed at dedicated location, exposed for one month and analysed using TLD reader at Secondary Standard Dosimetry Laboratory (SSDL), Malaysian Nuclear Agency. The obtained results showed, the average cumulative dose per month and annual dose ranged from 0.04 – 0.16 and 0.08 – 0.38 respectively. The results showed that there were no significant increase as compared to previous continuing environmental programme (EMP) in 2017 and the annual dose is also below the stipulated limit for public by Atomic Energy Licensing Board (AELB).
