A 8 hour period after the rain stopped till it socked into the ground.
What I think you are saying is you noticed a little higher than normal background after rain when the meters were in close proximity to the ground,
right?
Thats par for the course.
If your setting is on milli-rems then that reading is a a little higher than normal background and nothing to worry about. Not to say there isn't a
higher reading at the ground around gutter downspouts, storm drain grates or outlets, radiators, air filters and fender wells on cars, furnace or air
purifier filters, etc. There are a lot of places to check for higher than normal readings around us. The key to understanding the readings is to know
how and when to look for anomalies.
Obvious places to monitor are milk, unwashed lettuce leaves, bottom of shoes, whatever. Think where dirt accumulates and thats where to look. Keeping
records on data from measurements taken over time with calibrated meters then lends to noticing sudden spikes or increases over time.
How you take readings is as important. If you hold a detector three feet over the ground you will barely detect if the the ground is covered with
alpha emitters.
If you sweep the ground and you get a spike then that can't be held accurate unless the reading is steady for longer periods, overnight even.
What kind of "geiger counters" are you using? Please include a model number other than just Civil Defense or Store bought… kaay?
