Hallam environmental radiation surveillance
Hallam environmental radiation surveillance
An environmental surveillance report is presented for decommissioned Hallam power plant. Statistical analysis shows that the spring data mean is significantly greater than the fall data mean for all water sources. The spring variation is also significantly greater than the fall variation. The water sources demonstrate homogeneity for spring and fall sub-surface sources. Surface water has significantly more radiation than sub-surface water. This may be attributed to increased tritium content in surface water due to atmospheric leaching. Finally, the surface water samples are in close proximity to Sheldon Station, a coal fired plant, and increased coal particulate matter may be increasing the environmental radioactivity. A linear regression model suggests spring readings are decreasing and fall readings significantly increasing from 1975 to 1987. The spring recharge water probably contains natural and man-made radioactivity leached from the atmosphere, as well as natural radioactivity leached from the soil and rocks. The lower mean and less variance for the fall data may better characterize the aquifer. 7 figs.
