![]() ![]() With the exception of Miami Bay, considered an elevated background radiation area that would benefit from regular monitoring, Penang island beach sands typically pose no significant radiological risk to the local populace and tourists visiting the leisure beaches. The measured data were compared against literature values and also recommended limits set by the relevant international bodies. ![]() The main contributor to radionuclide enrichment in Miami Bay is the presence of monazite-rich black sands. Guidelines for radioelement mapping using gamma ray spectrometry data. Following the IAEA guideline of the Sardinian granites, the knowledge of their natural (IAEA-TECDOC-1363, 2003), the gamma-ray spectroscopic radioactivity is basic for the evaluation of the amount of public analysis is performed by monitoring three spectral windows: exposure because people spend most of their time (about 80) 1.37-1.57 MeV for. The mean activity concentrations for 226Ra, 232Th and 40K at different locations were found to be less than the world average values, while the Miami Bay values for 226Ra and 232Th were found to be greater, at 1023 ± ± 96 Bq kg ̶ 1 respectively. IAEA (International Atomic Energy Agency), 2003 IAEA (International Atomic Energy Agency) 2003. Activity concentrations of primordial radionuclides in sand samples collected from the coastal beaches surrounding Penang Island have been measured using conventional γ-ray spectrometry, while in-situ γ-ray doses have been measured through use of a portable radiation survey meter. ![]()
