Raw Data from Saint Louis Neptunium 239 Detection Available for Public Analysis

To facilitate public analysis of the Neptunium 239 detection in the 9/14/11 Saint Louis fallout event,  the raw data from the Neptunium 239 detection analysis is presented below.

Further analysis  spawned by public input indicates that the measured spike at approximately 92 hours into the testing is NOT from Radon 222 daughter in-growth. Moreover, the presence of on going detectable levels of Radon 222 (+ daughters) in the sample is ruled out by the lack of an activity spike in the unshielded sample taken at 9/15/2011 17:06:50.

Data measured with a Medcom Radalert Inspector
Conversion factor 1mR/hr = 3500 CPM, based on Cs 137
