Wild Boar Radiocesium Concentrations in Fukushima Prefecture

3,941 individual wild boar records from Fukushima Prefecture, collected between fiscal years 2011 and 2025. The dataset includes capture dates, locations, biological attributes, and ¹³⁷Cs concentrations for analysis of radioactive contamination in wildlife.

Use Cases

• Analyze temporal trends in ¹³⁷Cs concentrations using capture dates across the 15-year period.
• Model spatial patterns of contamination by correlating ¹³⁷Cs concentrations with recorded locations.
• Investigate relationships between biological attributes and ¹³⁷Cs concentrations to assess bioaccumulation factors.

Strengths

• Contains data for 3,941 individual animals, providing a substantial sample size.
• Covers a 15-year time range from FY2011 to FY2025, enabling longitudinal analysis.
• Includes a curated subset of 3,609 individuals with complete records for statistical modeling.

Limitations

• The dataset is small in file size (287.3 KB), indicating limited scope and potentially few variables per record.
• Unknown column count and structure limit understanding of available features without inspection.
