Let's be careful. I see essentially *no* connection between the electron's
mass and its radiation resistance.

Suppose we boost a charged object from velocity (v) to (v + delta_v), using
an acceleration that is uniform over some time interval (delta_t). Let's
consider (delta_t) to be adjustable while keeping (v), (delta_v), (m), and
(q) fixed.
-- We must impart to the object a certain amount of kinetic energy; this
amount is *independent* of (delta_t).
-- We must also provide enough energy to overcome the radiation
resistance, but this scales like (1/delta_t) so it can be made arbitrarily
small by spreading the acceleration over a sufficiently long time.

John I don't follow your point here. I understand that by making the time
required to attain a specific velocity arbitrarily long we reduce the
specific radiation resistance to a very small value. However this very small
value would be averaged over a much longer time. Doesn't radiation resistance
"store" energy of motion in a similar way that inertia does for particles in
motion. Thanks in advance for your patience with regard to this question.
