I didn’t realize the paper was linked! It specifically mentions:
600 Bq / kg
This is a unit of radiation / mass. Going by a WolframAlpha example, one cubic meter of “typical” emits soil about 10,000 Bq. 1 cubic meter of the tested soil emits about > 900,000 Bq, though the high end is an outlier:
So 90x above ambient soil radiation, it seems.
…This is not a lot! Dirt is not very radioactive, we are talking microscopic amounts compared to radiation sources like X-rat machines. You wouldn’t want to inhale a ton of the soil, but still.
Yeah it wasn’t that bad on the guardian’s part, papers have always written headlines that sell. And you absolutely 100% don’t want to inhale plutonium dust. It alpha decays with a lot of energy, which even in small amounts is a recipe for lung cancer. IDK specifics for how much it would take to get kicked up and be deadly.
