Yes, you're correct. My bad. Though, in my experience, "radiation" without a modifier almost always refers to the electromagnetic variety. But I guess that could vary depending on what circles one hangs out in.

- Sharlin 12y agoIME in physics, the term "radiation" usually refers to particles whose total energy is much greater than their rest mass. Not all free electrons constitute beta radiation; only those whose velocity is some considerable fraction of the speed of light. Massless particles such as photons, on the other hand, are always radiation according to that definition.
