Occupational Radiation Exposure Assessment in Indonesian Tin Smelters

Ilsa Rosianna's dataset, last updated in May 2026, contains an integrated assessment of annual effective radiation doses for workers at two tin smelters in Indonesia. The data includes measurements of external gamma radiation and internal radon/thoron exposure, with activity concentrations for radionuclides in raw materials and by-products. The total annual effective dose for most workers was under 2 mSv, but reached 20.72 mSv for slag handling at one site.

Use Cases

• Identify radiological hotspots in industrial processes based on slag handling dose measurements.
• Compare contributions of external gamma exposure versus internal radon/thoron exposure based on pathway analysis.
• Assess the concentration of radionuclides from the 232Th and 238U decay series in industrial by-products.
• Support the development of ALARA-based protection strategies for NORM management.
• Evaluate compliance with occupational dose limits, such as the IAEA recommendation, for specific job roles.

Strengths

• Dataset provides specific dose measurements, including a maximum of 20.72 mSv for slag handling.
• Includes quantified activity concentration increases, such as a 79-fold rise for 232Th from raw materials to slag at one site.
• Integrates data from two distinct exposure pathways (external and internal) and two smelters with different raw materials.
• Released under a permissive CC-BY-4.0 license.

Limitations

• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The dataset is very small at 10.1 KB, indicating limited scope or a summary table rather than raw measurement data.
• Geographic coverage is limited to two specific smelters in Indonesia.
