“…NORM dapat masuk ke dalam tubuh melalui inhalasi atau ingesti (penelanan). Konsentrasi radionuklida yang tinggi di dalam tubuh dapat menyebabkan efek kesehatan, seperti peningkatan risiko kanker, sehingga perlu dilakukan pengukuran radionuklida di daerah yang diteliti (Madzunya et al, 2020). Secara umum, paparan radiasi dari radionuklida tersebut tidak menyebabkan efek kesehatan secara langsung, namun secara perlahan dapat meningkatkan resiko kanker.…”

Sungai Batang Hari merupakan sungai terpanjang di pulau Sumatera yang mengalir melewati Provinsi Sumatera Barat dan Provinsi Jambi. Sepanjang Daerah Aliran Sungai (DAS) Batang Hari masih ditemukan lokasi aktivitas Penambangan Emas Tanpa Izin (PETI) yang beroperasi. Sumber air yang berasal dari sungai maupun bawah tanah di daerah penambangan emas dapat terkontaminasi radionuklida alam seperti Uranium-238 (238U), Torium-232 (232Th), Radium-226 (226Ra), Polonium-210 (210Po), Kalium (40K), dan Timbel-210 (210Pb). Pentingnya untuk menilai kualitas air yang dikonsumsi dari aspek radioaktif, maka perlu dilakukan penelitian pengukuran radionuklida 238U, 232Th, dan 40K pada air sungai, air sumur (bawah tanah), dan air minum dari daerah sampel yang dialiri oleh sungai Batang Hari yaitu Kota Jambi, Kab. Muaro Jambi, Kab. Tebo, Kab. Batanghar, dan Kab. Bungo. Sampel diukur menggunakan spektrometer gamma detektor High Purity Germanium (HPGe). Hasil penelitian menunjukkan konsentrasi aktivitas tertinggi 238U, 232Th, dan 40K masing- masing yaitu 0,1916± 0,05 Bq.L-1; 0,04±0,03 Bq.L-1; dan 0,68±0,04 Bq.L-1. Konsentrasi aktivitas pada sampel air berada di bawah batas ambang yang direkomendasikan oleh PERKA BAPETEN No. 9 Tahun 2009, WHO Guidelines for Water Quality 2011, dan UNSCEAR Report 2000 sehingga aman dan memenuhi syarat standar kualitas radioaktif air.

“…According to a study by the World Health Organization (WHO), uranium-238, thorium-232, and potassium-40 are some of the most hazardous elements that influence the environment. 8 Several studies have been carried out to identify a suitable and efficient sorbent for the removal of heavy metal ions and other contaminants. Natural inorganic materials, peat, peat moss, algae, yeast biomass, rice husk, nanomaterials, sawdust (SW), and others have been suggested.…”

The optimum conditions for the removal of uranium-238, thorium-232, and potassium-40 from wastewater and the discharge of nuclear facilities using multiwalled carbon nanotubes (CNTs) are described. The adsorption mechanism is mainly attributed to chemical interactions between the metal ions and surface functional groups of the CNTs. Batch adsorption experiments are carried out in order to study the effect of different parameters such as pH, contact time, initial metal ion concentration, adsorbent dose, and temperatures. Maximum metal removal (>98%) from solutions containing 20–120 Bq/L metal ions is achieved using a contact time of 15 min, a pH of 6.0, and 10 mg/L CNTs. The effect of temperature on the kinetics and equilibrium of adsorption on CNT particles is examined. Consistent with an exothermic reaction, an increase in the temperature resulted in an increase in the adsorption rate. Langmuir, Freundlich, and Dubinin–Radushkevich isotherms are applied to the data obtained at various temperatures. The Langmuir adsorption model is the best for data interpretations. The kinetics of adsorption reveals a pseudo-second-order mechanism. Thermodynamic parameters at 293 K (Δ G °, Δ H °, and Δ S °) for U-238, Th-232, and K-40 are −14590.7 kJ/mol, −6.66 kJ/mol, and 26.47 J/(mol K), −96,96.5 kJ/mol, −2.48 kJ/mol, and 14.17 J/(mol K), and −3922.09 kJ/mol, −1.32 kJ/mol, and 6.12 J/(mol K), respectively.

“…As a result, 40 K, 238 U/ 226 Ra, 232 Th, and 222 Rn are of relevance in terms of radiation protection, and their studies have gained a lot of attention around the world. Several studies have been undertaken in the last two decades to quantify radionuclides in soil that can be connected to the absorbed dose rate in air [3,5,6,21,23,26,32,38,39], among others. These findings provide a more comprehensive assessment of background exposure levels in various countries.…”

Currently, the mining industry in Tanzania faces significant challenges including the presence of radionuclides in the working environment. In this work, different indices were applied to assess the health risk of people living and working in the study area. The radiation hazards in the studied mining areas are compared with the recommended local and international guidelines. The health risk and mitigation measures due to radioactive elements exposure to mine workers and people dwelling in the mines is established. The hyper pure germanium detector (HPGe) was used for radioactivity analysis. The radon gas levels were measured using the Alpha Guard radon monitor. The results on radioactivity; mean effective dose; annual gonadal equivalent and absorbed dose; radium equivalent; internal and external hazard indices; alpha and gamma indices; and the radon gas revealed high values in mining areas compared to the control area. However, some of the levels of radionuclides along with their hazard indices are lower than the recommended international limits. The mitigation measures which include dust suppression using water spray and the use protection gears such as masks and gloves are recommended. The present study recommends follow up and further studies in the ASGM subsector.
