Perkiraan Dosis Radiasi Yang Diterima Publik Di Provinsi Kepulauan Bangka Belitung

Terrestrial Gamma Radiation Exposure in Bangka-Belitung Islands, Indonesia

“…The rapidly increasing number of illegal mines is a large contributor to the destruction of the Bangka-Belitung soil [14]. K in soil collected from the same site with present work have been previously reported [7].…”

“…The activity concentrations of natural radionuclides in soil of Bangka and Belitung islands have been previously reported [7]. Generally, the average and ranges of activity concentrations of radionuclides in soil collected from Bangka and Belitung islands are higher than the common areas world average, except for [8].…”

“…The sampling points were selected by dividing each of the total area of the Bangka and Belitung islands using a square grid as reported previously [7]. Geographical coordinates of sampling points were determined using a 60CHx global positioning system (GPS) map manufactured by Garmin.…”

“…In Belitung Island, mineralizations formed far from the granite bodies. The altitude of the island above the sea level during the Tertiary and Quaternary period also contributed to the weathering intensity, which influenced the characteristics and existence of the primary mineral deposits [2,7]. Additionally, the increasing tin mining activities by individuals and illegal mines in Bangka-Belitung islands may also be responsible for the enhanced radioactivity in the area.…”

The Investigation of ¹³⁷Cs Contamination in Soils of Aceh after the Tsunami

“…Since the absolute efficiency was employed in the same Marinelli beaker geometry and the same approximate density as the samples, the difference in the self-attenuation for gamma rays in the sources and samples was assumed to be negligible. Quality assurance was additionally guaranteed by regular participations in national and international intercomparison exercises [20].…”
