Indonesia's tin smelting industry was assessed for occupational radiation exposure from Naturally Occurring Radioactive Materials (NORM). The dataset, authored by Ilsa Rosianna and last updated in May 2026, integrates external and internal dose measurements from two smelters using raw materials with different tin contents. It reports total annual effective doses, with most workers below 2 mSv but one slag handling operation reaching 20.72 mSv.
Use Cases
- Identify radiological hotspots in industrial processes based on slag storage and smelting area measurements.
- Compare the contribution of different radionuclides (e.g., 232Th vs. 226Ra) to external gamma exposure based on activity concentration data.
- Evaluate the relative importance of radon versus thoron progeny for internal exposure in different work environments.
- Support the development of ALARA-based protection strategies using integrated external and internal dose assessments.
Strengths
- Integrates both external and internal exposure pathways, providing a comprehensive dose assessment.
- Includes specific quantitative findings, such as a maximum dose of 20.72 mSv for slag handling and activity concentration increases up to 79-fold for 232Th.
- Data is openly available under a CC-BY-4.0 license, facilitating reuse and analysis.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment for certain statistical analyses.
- The dataset is very small (10.0 KB), indicating limited scope or a summary table rather than raw measurement data.
