Evolution of radio-resistance is more complicated than previously thought:

The toughest organisms on Earth, called extremophiles, can survive extreme conditions like extreme dryness (desiccation), extreme cold, space vacuum, acid, or even high-level radiation. So far, the toughest of all seems to be the bacterium Deinococcus radiodurans—able to survive doses of radiation a thousand times greater than those fatal to humans. But to this date, scientists remained puzzled by how radio-resistance could have evolved in several organisms on our planet, naturally protected from solar radiation by its magnetic field. While some scientists suggest that radio-resistance in extremophile organisms could have evolved along with other kinds of resistance, such as resistance to desiccation, a question remained: which genes are specifically involved in radio-resistance?

    If you think radio-resistance is complicated, wait until you get to radio-impedance.

      Radio induction. Especially how radio stations try to induce you with advertising.

    It's only confusing to eggheads. Hard rockers know they evolved next to the metal station in my college.

    The recent movies explain radio-resistance. Like Godzilla, they came from a time when Earth was much more radioactive than it is now. :)

    It's not that hard to explain evolution of resistance to radiation in the mildly radioactive environment of Earth. Many of these organism can become dormant for enormous lengths of time. But when you're dormant you lose your ability to repair genetic damage from radiation. That means that an organism that's dormant for a year (or a century) effectively receives a dose of radiation equivalent to a much higher dose over a short period of time.

    I thought we've known the solution to radio resistance for years, maybe the youngsters have forgotten: video kills it.

    Obviously this evolutionary mutations has already occurred to some humans. Despite how blasted they are by radio commentary, politicians still get reelected.
