Abstract

Most ionizing radiation sources that are present in the environment expose people to it. One of the biggest contributors to that exposure comes from natural radiation sources. Cosmic, terrestrial, and internal radiations are all sources of natural radiation. A few artificial radiations that result from nuclear reactor activity, medical facilities, and various businesses have also contributed. Indonesia^s Java Island is where the majority of people live. A critical piece of information that can be utilized to assess radiation levels and potential sources of contamination is the evaluation of the natural background of nuclear radiation. Then, as information for the general public regarding radiation doses, it can also build a map of natural nuclear radiation in Java Island. In this study, measurements were made at numerous sites on Java Island, where a lot of people go and carry out their daily activities. The examination is carried out utilizing the Geiger-Muller-based GMC-320 Plus detector. The outcome will be displayed as a mapping area, the radiation level in CPM, and the radiation dose rate, which is displayed as the average level of background radiation.
