7. Analysis Our hypothesis was incorrect. Air pressure and radiation counts have a direct correlation. However data is unreliable because of averaging.

8. Improvements? Better communication for live feed. Better communication for live feed. Get a labquest Get a labquest GPS for altitude measurements GPS for altitude measurements Better intervals for counts Better intervals for counts
