I then chose three species, 3H (a pure beta emitter with no gammas), 18F and 22Na (both of which decay by both electron capture and positron emission) and was somewhat surprised to see them as having no betas or, in the case of the latter two, as undergoing electron capture with no mention of positron decay.
