That fungus is called Cladosporium sphaerospermum, and some scientists think its dark pigment – melanin – may allow it to harness ionizing radiation through a process similar to the way plants harness light for photosynthesis. This proposed mechanism is even referred to as radiosynthesis.
wait, are black people more radiation-resistant?
In terms of UV radiation cuaisng things like sunburn and skin cancer in humans yes.
At the scale when gamma radiation is being thrown around at high levels no.
Maybe slightly - but you are a fool if you test this.
Because I’m not black
Also, because you are a fool. They are not mutually exclusive reasons.
So IRL ghouls that get healed by radiation possible?
