We have reanalyzed the data from the June 6-7th, 2012 airborne radioactive detection in South Bend, Indiana.
The key findings are as follows:
- The termination edge of the Jet Stream was located over the radioactive detection area
- The high radioactive readings commenced after the 5 mph North wind dropped to zero mph.
- The high radioactive readings persisted for the entire 5 hours the wind was not blowing
- The high radioactive readings stopped when the wind picked up at 5 mph from the west.
- Normal radioactive readings continued for 40 minutes after the surface wind resumption ended the event.
- The bimodal "clipped" peak features and dropout shown in the 5 hour long radioactive detection are from a highly radioactive field saturating the detector's Geiger-Mueller tube.
- Hysteresis is evident on the saturation recovery condition side of the readings.
- A Weibull based radiation intensity distribution approximates both ends of the detection curve.
- High Beta radiation (electrons) likely tripped the reported Ground Fault Interrupt outlet.
- There is no simple power supply driven failure mode that can duplicate the above conditions.
- Higher airborne radioactive readings have been detected along the Northern Hemisphere Jet Stream.
The key steps forward are as follows:
- Perform sample swipes in and around the specific area Geiger counter area
- Identify the specific detection location within at minimum a 5 mile area.
- Identify the specifics of the Geiger counter and associated setup.
- Attempt to replicate the 5 hour long detection via a power supply / GFI failure
- The airborne fallout was from a small but very radioactive source near the detection location
- A near source scenario would likely be South-East of the location, or possibly North of the location.
- A far source scenario would be Jet Stream born
