I see a huge jump between the 17th and 18th but I have no idea what that means. Can someone please explain? Or is the jump minor, and the axis is to blame for the seemingly large change?

I have no idea either, but I'd guess it's an insignificant change based on this: https://news.ycombinator.com/item?id=13676862

Silicon Valley is far from "Europe" though...

Note the scale. The "huge jump" is from 8.3 to 8.7 uR/h, just a few percent.

nevertheless it seems quite significative, and I would love to get some explaination for this kind of jump.

Without any context or explanation, the link isn't really useful nor interesting. Is a daily average change of roughly 0.5 uR/h meaningful? We can see from the hourly chart above that short-term fluctuations can be between roughly 0 and 20 uR/h, what is a meaningful change? It's currently very unclear what the linker is trying to say with sharing the link and why it was shared to begin with.

agreed, there's 0 context here and I'd be highly interested to know why the graphs are being up voted.

Could it be the storm is bringing radiation from Fukushima?

Would downvote if I could, anything below 10 uR/h is background radiation. Sniffles posted a link to a rad monitoring device doing it's thing, and not showing anything out of the ordinary.

I think it's great that the chart is completely ordinary. Imagine how terrible it'd be if it suddenly became fascinating.

  Gamma Gross Count Rate represents how many gamma rays the monitor detects each minute.

The levels looks normal to me.
