Abstract

Research has been conducted on the determination activity of natural radionuclides at hot springs in Bogor Regency, West Java. This study aimed to determine the concentration value of natural radionuclide activity in hot springs. This study used water samples taken from water samples taken from water in two different hot spring locations, namely in Gunung Panjang Hot Spring and Gunung Panjang Hot Spring. Activity concentrations were measured using an HPGe gamma spectrometer for radionuclides 238U, 232Th, and 40K. Activity concentrations for radionuclide 238U ranged from (0.13 ± 0.01) to (33.82 ± 0.24) Bq/L, for 232Th ranged from (0.08 ± 0.01) to (100.30 ± 0.01) Bq/L and 40K ranged from (0.18 ± 0.01) to (416.84 ± 0.09) Bq/L. The concentration values of 238U, 232Th, and 40K are still below the specified threshold. The activity concentration limit of radionuclides recommended by PERKA BAPETEN No. 9 Year 2009 on Intervention Against Exposure from Technologically Enhanced Naturally Occurring Radioactive Material is 1000 Bq/L for 238U and 232Th and 10,000 Bq/L for 40K.

Abstract

Utilization of various radioactive sources in Indonesia, including nuclear fuel, nuclear waste, and radioactive minerals, has significantly increased to support research, industry, and healthcare services. This usage necessitates an evaluation of environmental impacts, particularly the increase in background radiation in the context of radioecology. Radionuclides like cesium, which are highly soluble in water, can be released into marine waters through leaks from nuclear power plants, radioactive waste, and military weapons tests, potentially harming marine ecosystems and the food chain. Therefore, periodic monitoring of underwater radiation exposure is crucial. This study aims to develop a gamma-ray radiation dose monitoring system underwater using a wireless Geiger-muller counter and LabVIEW-based interface. The system comprises a Geiger-muller counter for measuring radiation doses, an nRF24l01+ module for data transmission, and a LabVIEW application as the display panel. Testing was conducted by submerging a radioactive cesium source into a water tank with varying distances and depths. Radiation data were measured by the Geiger-muller counter, transmitted via the nRF24l01+ to the receiver, processed by Arduino Uno, and displayed in LabVIEW. The LabVIEW application also provides alerts if the dose exceeds the threshold and records the dose values. Test results showed the lowest measurement success rate of 17% at position 7 and the highest of 30% at position 1.
