Radiation does not solely mean ionising radiation. Yes, people often leap to ionising when radiation is mentioned, but they're wrong.
Radiation is a technical term being used correctly in an article written for an audience likely to know that it refers to satellites unintentionally radiating in bands they're not meant to.
What surprises me is that there's no regulations that cover this, I guess when satellites were the domain of government, they didn't feel the need. But it'd be good if regulators in countries hosting space programs caught up.
PS, light is also ionising radiation at the higher end of the spectrum.
