The article talks about fungi been attracted to ionising radiation. Per wikipedia:

https://en.wikipedia.org/wiki/Ionizing_radiation

Ionizing (or ionising) radiation is particle or photon that has enough energy to detaching electron from atoms or molecules. It includes all the usual high energy radiations such as Gamma, X-rays, high energy UV, alpha, beta, neutron et al. HN high energy physicists can correct me, sounds like it is not any particular category of the harmful radiation from a nuclear disaster, it is all of them.
