  We address the old question of whether or not a uniformly accelerated charged
particle radiates, and consequently, if weak equivalence principle is violated
by electrodynamics. We show that radiation has different meanings; some
absolute, some relative. Detecting photons or electromagnetic waves is NOT
absolute, it depends both on the electromagnetic field and on the state of
motion of the antenna. An antenna used by a Rindler observer does not detect
any radiation from a uniformly accelerated co-moving charged particle.
Therefore, a Rindler observer cannot decide whether or not he is in an
accelerated lab or in a gravitational field. We also discuss the general case.
