Yeah, this is standard practice everywhere for home buyers.
If you rent, you should still get a Radon test done in your residence. You can do it yourself, no reason to wait for your landlord (I personally have an AirThings meter but you can also get single-use tests that a cheaper). Anything above 2 pCi/L is concerning and is remediated by regularly refreshing the air in your home; above 4 is cause for installation of a radon mitigation system.
Basements are particularly vulnerable, as well as first-floor rooms.

Everywhere? The risk varies significantly by where you are in the world. Where I live, I’ve never heard of anyone getting a radon test. I was aware this was a thing in some countries, but our soils have very little compared to some countries. Our average radon in homes is around 23 Bq/m3 which is around half the average in the US (50Bq/m3), and the EPA suggests action if in the 75-150 range. (Which is quite a range!).
Even in my state I don’t think it’s required everywhere. In the mountains and the Piedmont there is a risk although it’s not common, but I think in the coastal plain on the sandy soil it’s uncommon. IIRC for our state the more granite in the ground the higher the risk. Having a crawlspace foundation is also better than a basement or a slab foundation because it gives a space that can easily be ventilated before the gas enters the living space of the home.
I think I saw a study once that granite countertops may offgas some radon. Maybe there’s not enough granite in the average home to cause concern.
Could easily be better weatherproofing
One of the reasons I never worried about radon is I live in an older house that leaks lots of air.
Its really only relevant if you live on radon producing rock, like granite.
2 pCi/L
Wut? That’s such a weird combination of units for an American system.
Deep in the heart of the Radhausberg mountain, nestled in the majestic landscape of Austria’s Hohe Tauern mountains, our radon thermal tunnel unfolds its natural healing powers.
Innovative.
Here is one study: pmc.ncbi.nlm.nih.gov/articles/PMC10876773/
If there was no benefit these caves wouldn’t be allowed to operate, and they do make sure that patients recieve the correct dosage.

In this randomized, placebo-controlled cross-over trial we aimed to investigate if radon spa therapy exerts more pain relief than exposure to warm water alone. In addition, immunological parameters were assessed in both treatment groups. In the ...
The risks aren’t the same everywhere, but even if you live in a low-radon area, your specific location may still contain high levels of radon. Best to just do a radon test on your house to be sure. You can get a home test for cheap.
