I mean, if he's absorbing the corona into one spot, aka, the entire corona, then I figure he'd be absorbing the radiation that is also emitted from it, along with the heat. I figured it'd just be assumed that the heat comes along with the radiation, as he's absorbing the entire thing's energy. I can make a CRT or a QnA thread to find out, as I'm not sure.
Also high-doses of X-Ray radiation can be fatal, and the corona emits not only that but also extreme amounts of Solar Winds, which are also radioactive.
