On August 8th we took a paper towel swipe sample from a piece of sheet metal left out in the rain; that swipe returned our 3rd highest radioactive reading since Fukushima began, ninety one times greater than background radiation.
Since then, we have continued to run continuous Geiger counter readings of both the sample and background radiation. Those readings have continued to show that radioactive fallout remains detectable on the sample. (see video below)
We now update the results from our previous video with an additional 5 days of continuous sampling. As seen in the graph above, there continues to be a persistent long half life radioactive rain remnant remaining at 0.04 counts per second (2.4 counts per minute)
