“…It was understood that the beach sands in several other countries such as the Guangxi Province, China, and white sand in Langkawi, Malaysia had a slightly smaller average I value of 0.17 and 0.19 (22,34). However, there was also a report that the beach sand in other areas such as Southern India had a higher value of I (2.35) than this study (35).…”

Introduction: Beach sand is one of the widely used aggregates in construction, especially in coastal areas. However, beach sand contains a hidden risk, namely radioactive hazards. This research will analyze the radioactive activity of nuclides 226Ra, 232Th, and 40K on beach sand and calculate the health risk potential in radiation exposure to the household. Methods: Beach sands sampling was carried out on Madura Island, Bali, and Lombok in 2016. All samples were ovensifted and then put into Marinelli to be chopped using high-purity germanium (HPGe) gamma-ray detectors for three days. Results and Discussion: The average of 226Ra, 232Th, and 40K radionuclide activity on the beach sand in Madura were respectively 31.46 Bq/kg, 40.12 Bq/kg, and 334.04 Bq/ kg; in Bali were 25.10 Bq/kg, 7.71 Bq/kg, and 165.15. Bq/kg; and in Lombok the amount is 25.88 Bq/kg, 8.25 Bq/kg and 171.99 Bq/kg. The calculation of the radium equivalent (Raeq) value on beach sand in Madura, Bali, and Lombok has the highest value of 132.72 Bq/kg, 54.06 Bq/kg, and 55.92 Bq/kg. The gamma index (I) in Madura, Bali, and Lombok was 1.02; 0.39; and 0.40. For the calculation of Hex and Hin in Madura, Bali, and Lombok, the highest were 0.38; 0.15; 0.15; and 0.48; 0.23; 0.24. Conclusion: The activity of the three types of natural radionuclides from the three regions is still below the threshold value. Analysis of potential health risks showed in the gamma index value (I) indicator, which exceeds the safe threshold in the Madura beach sand sample.

HPGe γ spectrometry method was used to measure the natural radioactivity levels ( 40 K, 232 Th, and 226 Ra) of the beach sand samples from Cleopatra Beach and Damlatas Beach in Antalya (Turkiye). The mean 40 K, 232 Th, and 226 Ra radioactivity levels of the studied samples were calculated as 276.88 ± 17.24, 25.04 ± 2.88, and 17.06 ± 1.68 Bq/kg, respectively. Being below the radiation limits, these values indicate no risk in terms of public health. Moreover, the radiological risk parameters, such as excess lifetime cancer risk, radium equivalent activity (Ra eq ), absorbed γ dose rate (D), annual effective dose equivalent (Ea ed ), γ index (I γ ), internal radiation hazard index (H in ), and external radiation hazard index (H ex ), were calculated. The values of all of these parameters were found to be below the internationally accepted radiation limit values. In addition, distribution maps showing the radiological situation of the region were generated although they did not pose a hazard to public health. No results were found in the analysis processes related to artificial radioactivity.
