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.
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?
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.
