Environmental Radiation Surveillance West Valley Water Gross Beta Readings for Erdman Brook: Beginning 2009

This is a graph of the gross beta concentration in water at the swamp drainage to Erdman Brook near the West Valley Demonstration Project site. A column has been added for values which can be graphed. Readings where a less than value is displayed show a value that is less than the detection limit of the measurement method and are essentially equivalent to 0. Variations in detection limit are due to variations in sample collection and measurement instrument performance.
