Connecticut Environmental Radiation Monitoring Results from 2008 to Present

Quarterly environmental radiation monitoring results reported in millirem, as defined by Connecticut state regulations. The dataset, provided by the State of Connecticut's Department of Energy and Environmental Protection, contains records from 2008 onward, with earlier data available in hardcopy. Results below the minimum measurable quantity are recorded as 'M', and the data includes a disclaimer regarding potential errors from entry, migration, or equipment failure.

Use Cases

• Analyzing long-term trends in environmental radiation exposure based on quarterly time-series data.
• Identifying potential anomalies or equipment failures based on records marked 'M' for below minimum measurable quantity.
• Assessing data quality and completeness for regulatory reporting based on the described error sources.
• Modeling seasonal variations in gamma exposure based on calendar quarter reporting periods.

Strengths

• Provides a continuous time series from 2008 to the present, offering over 15 years of data.
• Explicitly documents data quality disclaimer and specific potential error sources like migration losses and entry errors.
• Reports data on a standardized calendar quarterly basis, facilitating temporal analysis.

Limitations

• Row count and column definitions are unknown, which limits suitability assessment.
• Data prior to 2008 is stored in hardcopy and not in this database, creating a temporal gap.
• The description warns of potential errors from data entry, migration, and unreported monitoring results.
