“Things” are radioactive and emit radiation. Fungi eat those things. Do the digestive processes of the fungi somehow alter the atomic composition so the fungi not become radioactive? The article is not very clear. Usually when someone absorbs radiation, that person themselves become radioactive. That is why after my PET scan I was told not to handle babies so my radioactivity wouldn’t affect them.

Nope. The melanin in the fungi absorbs ionizing radiation and converts it into energy like a solar cell converts light into energy.
A fungus that “eats” radiation is now radioactive.
