Connecticut Environmental Radioactivity Monitoring Results from 1998 to Present

Connecticut environmental sample records for radioactivity, measured in picoCuries per gram (pCi/g), from 1998 to the present. The data is provided by the State of Connecticut Department of Energy and Environmental Protection (DEEP) and includes calculated uncertainty values for measurements. Records prior to 1998 are stored in hardcopy and can be requested via a Freedom of Information Act (FOIA) process.

Use Cases

• Analyze long-term trends in environmental radioactivity based on sample results from 1998 onward.
• Assess measurement reliability based on reported error results and uncertainty values.
• Identify potential data gaps or anomalies based on the described sources of error like data entry or migration issues.

Strengths

• Data covers a long temporal range from 1998 to the present.
• Results include calculated uncertainty values for sample measurements.
• Data is provided in multiple machine-readable formats (XML, RDF, JSON, CSV).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The data quality disclaimer explicitly notes potential errors from data entry, migration, and missing results.
