The enclosed package represents radiation data collected with the fixed-wing aircraft (C-12) off the east coast of Japan on three separate flights dated April 5, 2011, April 18, 2011, and May 9, 2011. The data were collected with an array of large thallium activated sodium iodide (NaI(T)) crystals and associated readout electronics to produce time and location referenced measurements. These results represent raw data that have not been validated but not calibrated to physical units. They do not include any further evaluation.
