England and Wales data contains estimates of activity concentrations for naturally occurring radionuclides (40K, 238U, 232Th series) in soil, stream sediments, stream waters, and non-human biota. The dataset provides both geometric mean concentrations from measured samples on a 5 x 5 km grid and extrapolated surfaces for complete geographic coverage.
Use Cases
- Model spatial distributions of 40K, 238U, and 232Th series radionuclides in soil and stream sediments across England and Wales.
- Analyze relationships between radionuclide concentrations in stream waters and underlying bedrock geology.
- Assess environmental exposure for non-human biota, focusing on ICRP Reference Animals and Plants, using targeted sampling data.
- Compare measured geometric mean concentrations on a 5 x 5 km grid with values from geologically extrapolated surfaces.
Strengths
- Data provides nearly complete geographic coverage for England and Wales through geological extrapolation.
- Includes measurements on a systematic 5 x 5 km square sampling grid where available.
- Covers multiple environmental media: soil, stream sediments, stream waters, and non-human biota.
Limitations
- Underlying geochemical survey data for England and Wales is described as incomplete, requiring extrapolation for full coverage.
- Data for non-human biota is from targeted sampling and reviews, not systematic national-scale surveys.
- Specific sample counts, row numbers, and column details are unavailable.
Provenance
