WOW!!!!! You really need to set up a station online for netc ASAP!!!
I looked around you and found no confirmation on these extreeemly high readings.
I wonder what's causing this!!!
Did the counter get wet during the rain?
Please tell us about the location of the read shown in the photo...
ie: Outside or inside, time of day/night, and date!!!!
Here's the page with instructions and software to put your counter online.

This is a very important step for you to take as we may can rule these spikes out (hopefully) or confirm them (hope not!!!)...
You should also get a second counter to confirm the counter is not malfunctioning!!!! Don't know about your budget but this is a must at this point. If these reads are real you've got a real problem. Get a 200 and hook it to the internet cheaply ($65)... Also get a radon test kit.
