Environmental Radiation Surveillance Nine Mile Point and James A. Fitzpatrick Air Readings: Beginning 2009

This is a graph of the iodine-131 concentration in air near the Nine Mile Point and James A. Fitzpatrick facilities. You can view other years by changing the "Sample date" filter and typing in the year you wish to view. Increases in concentration during March and April 2011 is due to the Fukushima accident. Increases in concentration that do not have a comment are within normal ranges. 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. For more information please visit http://www.nyhealth.gov/radiation.
