Radioactive rain

We've been measuring the radioactivity in rain water in Illinois. We discovered possible evidence the radiation may not be local radon progeny. We conducted two rain sample test's on 11-26-11. More rain test's will be conducted on this issue. You can watch our test here

The video "radioactive rain pt10" is a sum up video of "radioactive rain  pt7, pt8, pt9.

The graph below shows the results of the test. The first rain sample was tested at 3:10pm(15:10). The second sample was tested at 7:45pm(19:45). This was from the same rain storm. The jet stream moved over our area after the first wipe. The half life is short, this fact may indicate radon, but the jet stream seemed to influence the radioactivity.
