* 24 hour averaged graphs used to be posted here on the 16th day, the end of the month, or within 24 hours of an event, but now I'm doing periodic "spot checks", using my reborn Medcom "Inspector" Geiger counter. It's set to tally 100 minute counts in the same outside station (painted white, 40 inches above the ground) as in the past. This might be done every day if something's going on in the world. I can no longer see or note minute long counts of 33 (and up).

These counts should be done at roughly the same time of day and during the warmer part of the day (in deference to the Geiger counter's electronics). Whether inside the house or inside my outdoor station, the GC remains inside a sealed ZipLoc baggy with desiccant. Geiger counters like mine tally mostly gamma rays plus maybe muons and energetic beta, but no alpha. I might catch some lower energy beta when I check an air filter in close proximity.

* My 100 minute counts are only significant to two figures, so I'm now reporting only in whole percentage points --which has been the visual resolution of my posted graphs.

* Past monitoring graphs & comments.
* Other radiation monitoring networks.

* The nuclear power industry is staging a come-back, by way of "small modular reactors" ("SMRs"), which would be manufactured, shipped and assembled on site, rather than custom built. One design (backed by Bill Gates) uses (scary) high temperature molten sodium for the initial heat transfer/cooling/storage loop. Another SMR design, the NuScale project, was hatched right here in Oregon and has already gained a lot of federal approval/backing. Here's an article at Mother Jones:

Radiation Monitoring

~ 2021/12/26: A 100 minute count at 98% of average, starting at 13:30 hours PST (UTC/GMT minus 8 hours). We're having rainy cold days, but when I charted for temperature (and another time for rain), there was no correlation (despite the flutters seen in Germany's system during rain storms).

~ 2022/01/02: A 100 minute count at 94% of average, starting at 13:24 hours PST. Very little rain now. Solar cycle #25 is getting started plus there's a minor stream of solar wind hitting the Earth (which repels cosmic rays). Also: my long term baseline (which was done indoors) for the Medcom GC is rather dated (14.82cpm from an SBM-20 GM tube).

December - 2021

~  2nd: 33cpm peak at 18:26 hours (isolated).
~ 12th: The computer dedicated to tallying counts from my outside station suffered the Black Screen of Death, so I'm ending this series of graphs. I'll keep this and the older graphs page posted, should anyone wish to harvest data from them.

* I suggest:

> http://www.gmcmap.com/

--for the northern hemisphere and:

> http://sccc.org.au/archives/2630

--for the southern --as replacements. At these web sites you can access current readings as well as station histories, although you'll have to determine station cpms as baseline percentages on your ownmanually. (I'm not sure what the GMC station averages represent. Find out.)

November - 2021

~ 12th: No new graph yet, but the daily average dropped to 94.6% (below my arbitrary 95% threshold) this morning. The Sun is active, but on the far side.

July - 2021
~ 16th: This graph is very calm due to solar activity and solar wind pushing primary cosmic rays away from the Earth. What remains might be the true "base line" at about 96% --which could be due to local activity in/from the soil or even contamination inside the G-M tube I'm using (an M4011). For what it's worth, nearly all stations in the network (Radiation Network) I once belonged to reported a very similar, minimum level of radioactivity. So does Germany's government network of $3000 G-M tubes. As you can read elsewhere on my radiation pages, I've tried and failed to run this "96%" to ground. It's been 10 years along and I don't know what I'm counting.
