0.1 microsieverts (uSv) per hour is normal background radiation rate. Right now in my apartment (far from Ukraine) the dose rate is 0.12 uSv/h.

Is there a map service you're using to find the radiation levels at your apartment?

Nope, it's from Geiger counter on my desk.

Good lord, I love the understatedness of this comment.

?

It’s a Geiger counter. It’s cheaper than having an oscilloscope, which wouldn’t be “understated” either.

Do YOU have a geiger counter on your desk?

Well, I just ordered one, which was not a thing I expected to do when I woke up today.

We'll see if it actually ships; seems lots of people have the same idea right now.

The seem to be like £100 on amazon.

Yeah, but the fact that a Ukranian actually has one. I was going to make an "In Soviet Russia..." style joke, but a quick reading of the room suggested not good timing.

Commenter literally said “far from Ukraine”. What are you talking about?

oh, you're right. i totally missed the word far on initial read. totally changes the everything.

To be fair, I am around 500 km from the westernmost border, so not that far in American terms. We were affected by the Chernobyl disaster.

Most recent wayback machine sample I could find https://web.archive.org/web/20220226013028/https://www.npp.z... shows comparable to right now

Can't say historical, but 1,000 μsv/year is the annual limit / point at which increase cancer risk exists.

Fukushima disaster levels were 400,000 μSv/h at peak. Short term dose of 10,000 μSv causes radiation sickness but probably not death. Beyond that it gets worse.

I can say historically, background is 1,000-3,000 μsv a year depending where you live.

According to the Linear-no-threshold model [1], any level of radiation, no matter how small, causes cancer. According to this model, the 1,000 μsv/year of normal background radiation already cause cancer for 1% of people. And any additional dose increase the risk further.

However this model is contested. And the analysis on the cancers incidence in Hiroshima and Nagasaki and Chernobyl seems to indicate that this model is flawed. The exact model is difficult to estimate because of the low number of extra cancer is lost in the noise.
