Can any organisms see non-electromagnetic radiation?
Some fungi have radiotropism; they grow toward radiation sources. Melanin-expressing (melanotic) fungi migrate toward radioactive sources, which  enhance their growth. According to this paper.

These Melanotic fungi inhabit some of the most extreme habitats on earth such as the damaged nuclear reactor at Chernobyl and the highlands of Antarctica, both of which are high-radiation environments.
Radiotropism was triggered primarily by gamma radiation, but it is possible that both alpha and beta radiation could be  “ sensed ” by the fungi as well.

It seems like these melanotic fungi can detect gamma and beta or alpha that they can use as energy source.
