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.
