Does a charged particle in free fall radiate?

[pellman]

"Accelerated charges radiate."

That much-repeated phrase is the extent of my familiarity with radiating charges, though I am trying to bring myself up to speed on the Abraham-Lorentz-Dirac force.

Well, in relativity theory gravity is locally equivalent to an accelerating frame. so if we are in the falling elevator, do our charges falling with us in the elevator radiate? by the equivalence principle they should not, correct?

But in that case, stationary charges in a gravitational field are equivalent to accelerating charges in flat spacetime. So do stationary charges radiate under the influence of gravity?

Have you seen this recent thread? https://www.physicsforums.com/showthread.php?t=369612 Seems like the same thing to me.

Thanks. I will make any further posts on that thread.
