Yeah, and I was hoping that you could still look at high-level averaging over a country ("maybe the bad data will average out") but when I looked at a few hotspots it appears that those all came down to a couple uncalibrated-looking devices.
Not very useful or interesting in its current form, unfortunately.
Yeah I checked some tracks and it basically looked like the longer someone spent in a place, the higher the readings got. Maybe when the device doesn't get a lot of ventilation it starts to misread.
Pretty much, there are no shortage of ways to merge such data badly.
Many devices, uncalibrated and drifting, poor time normalisation to address counts accumulating when lingering, ... ffs they probably don't even adjust for cosmic or radon ...
( TBF the last two are pretty picky objections unless you're going hardcore geophysical professional )
Your general point is true, but in this case the devices are not really sensitive enough for radon to matter and the same is usually true for cosmic radiation.
When capturing open-air terrestrial tracks they are more or less uranium and thorium detectors.
From my observations it also seems to vary a lot depending on how the person recording behaves. Some people just walk around logging reading along the way. Others go out of the way to find interesting above background level radioactive objects and place the measurement equipment right next to those. Like finding 2 pieces of granite having 6x the background level in a giant pile of other rocks.
Another interesting pattern I saw while browsing around was increased level next to every fancy cast iron light fixture along a specific bridge. The bridge was made mid 20th century so I don't think they are old enough to have used thorium gas light mantles.

I think if this is only what they allowed it would be a useful since it would measure real world exposure.
I apologize if this is answered in the PDF, but I couldn't find an explanation there - any idea why fairly large chunks were omitted from the map? Some of them seem like population centers, others look like nature preserves.
It's interesting that Crocodile Dundee doesn't actually use the "That's not X, this is X" pairing [Dundee says "That" not "This" both times] but that's what we end up remembering and what imitators do to reference that line.
This one isn't on Wikipedia's list (at time of writing) unlike "Play it, Sam. Play 'As Time Goes By'" or "Why don't you come up sometime and see me?"

I left at the terms of service. I just wanted to see a map, it’s not worth trying to figure out what rights they want to take from me in order to do a quick browse.
If anyone want to fund a homeless guy buying one of these devices to use while he drive around the United States I could sure add a lot of contribution to the science. Let me know. I would love to help with this and be somehow useful in a society that finds me useless.
> Radiaverse turns those tracks into one shared map, with the places worth knowing about described by the people who found them.
This Claude sentence would be greatly improved by deleting everything after the comma. That clause adds nothing informationally and in some sense is using a very weird definition of describe and found.

This is a radiation map of Australia: https://www.ga.gov.au/bigobj/GA13928.pdf ( gridded data available for d/load )

The official stance was to keep no count and so the count remained NaN.
If all the data is crowdsourced it’s probably the German Atom-Angst

who knew we kept such things just lying around :)
