I thought everyone would find it interesting to see my NETC station (South Beloit Illinois) outside radiation monitoring graph compared to the NETC St. Charles Illinois outside radiation monitoring station.
Both stations are using the same type of geiger muller tube even though my stations geiger counter model is the GMC-200 and the St. Charles station is the GMC-300E model.
Both stations have the geiger counters outside 24/7 on the face of a HEPA air purifier to allow us better detection of the radiation present. They are both shown as a one week 1-hour graph. View both graphs and be amazed how similar both are, these stations are 67 miles part from each other. I'm so thankful to the St. Charles station operator. His stations setup makes a perfect station to compare my stations readings with.
Here is a screen shot of my station:
