  Detecting thermal Unruh radiation from accelerated electrons has presented a
formidable challenge due not only to technical difficulties but also for lack
of conceptual clarity about what is actually seen by a laboratory observer. We
give a summary of the current interpretations along with a simpler heuristic
description that draws on the analogy between the Unruh effect and radiation
from a two-level atomic system. We propose an experiment to test whether there
is emission of thermal photons from an accelerated electron.
