Any radiation weak enough to be stopped by living tissue will not be strong enough to go through the entire rock and iron bulk of the planet.
Bulma says in the manga it's a faint electromagnetic pulse the radar is tracking. The radiation does not have to be strong for her to track. Her technology could be advanced enough to pick up that weak signal.
If you noticed, the Red Ribbon army used large computers to track the balls. And even then they were in inaccurate. So Bulma was able to make the same tech more accurate and portable. Again, she's a genius (and part wizard apparently).
So she would be capable of making a Geiger counter in New York and having it react to a cellphone in Siberia for example.

We can't even put a car in a capsule, but can track a small cellphone in real life. So I can't see how it would be impossible for her to make tech advanced enough to pick up a weak signal in DB. If it was real world, Bulma would have been able to create the same type of tech for GPS. Only smaller and able to compenstate for the limitations of the current tech.

I'm sticking with "magic radiation", personally.
I understand what both of you are saying. But I think they may be playing down the logistics in how radiation works to put over Bulma's technological prowless.
