Although, since we have the Ca'Non example of:

Painstiks ... emit a highly charged shock for the express purpose of
inflicting pain. S32

This sentence also provides another example of later canon changing earlier canon. When we got the new word rIS, MO made this clarification:

LLL: How is this different to tlhuD "emit radiation"?

MO: {rIS} originally referred to emitting sound only. Later the meaning
was extended to mean emitting any sort of signal – sound, radiation,
smell, etc. {tlhuD} refers to radiation only.

In the example sentence, tlhuD is used with electricity. (Although perhaps a jolt of electricity is close enough to radiation -- that is, a discharge of energetic particles -- that it still counts.)
