The average background radiation count for the past week was 11.66.
For the past hour, the average count per minute was 11.82. This is pretty normal.
The minimum of one CPM occurred on Sunday at 8:51 pm.
The maximum of 36 CPM occurred on Saturday at 1:42 pm CDT. This is a very high count, and outside the normal levels. It is still very remotely possible that a random group of events might produce such a count, so we examine the levels around that time to see if anything else out of the ordinary occurred.
There's a 9 count, 12, 10, normal, normal, but here is a 19 and a 22 count, which are normal but high, and a couple of minutes after the 36 count, there is a 29 CPM, at 1:50 pm. A 29 count would have been the high count if the 36 hadn't been, so we have several high counts in the vicinity of the 36 CPM reading, before the radiation level settles back down to normal. To really scientifically conclude that it was "an event", I would have to run some programs that would process the data through some statistical tests, but this gives me a good basis for concluding that something substantial happened to the background radiation level at around 1:42 pm last Saturday. What was it? I don't know. I'd have to check the barometer reading, the solar flares for the past couple of days, and possibly shipping in the port, or train shipments on the tracks a block away, or - wait, when did North Korea explode its nuclear test recently? Could that possibly be the cause? That would be very cool.
It is kind of like looking at a picture of lightning -- some vast outburst of energy flashed by my "camera" last Saturday, and I caught a picture of it.
