I'm starting this thread to (hopefully) get unexplained readings from the map all in one place.

Hopefully (together) we can begin to figure out a strange spike or other unexplained reading(s).

It will (at the very least) be interesting to hear the theory(s).


If your counter gets listed here jump into the conversation and maybe we can all learn something about (and take action to correct) any unexplained and/or faulty reading(s) quickly.

Here's a couple to get us started...

http://netc.com/chart/view.php?n=1%3AEB59F343 Oak Harbor
I've been curious wondering if this is a reliable monitor as far as it's history. I don't see any other readings on NETC (within wind direction dispersion, known nuclear facilities or military bases nearby) that would correlate with the spikes. My son actually suggested a possible *not for public news* military experiment or exercise or sub near it.

I can always tell if any of my own Geiger count increases are from Fukushima via jet stream and weather patterns. Mine haven't really increased, and don't go along with Oak Harbor increases potentially making it over the Cascade Mt range. BTW my PRM9000 average stays about .11 or .12uSv/h, spikes after rains popping up to .25

I lurk often here but first time I've had a question. Thanks in advance. Great site.

Wow a really crazy looking "roller coaster" chart...

...I'd guess (purely a guess) it has to do with sunlight hitting the unit itself.

...Most likely Cosmic Rads as we have had solar activity (lately) as well...

Looking at the times it spikes it makes since. There is no description for the location and unit type so we simply can't tell anything (for sure) other than it's a strange read.

Also, you can see some down time late last month and again April 1st...

A good possibility it was moved to a different location in the home (or the yard).

Also notice there is no lingering rise in count. You would expect to see a real increase in averages from deposition of materials if this were a real reading.
Average is 15 and that is good for a GM like the 300.

The sub theory is not plausible or almost anyone would be able to find em...
...The shielding is so good on a modern sub you couldn't find one (if it was) in your backyard pond using a GM counter (the surrounding water helps shield too).



Anybody know the operator of this one?

It would be nice if someone would contact him/her.


Good one Teri...
