Albert Stevens’ Paintbrush

Origins
Albert Stevens was a house painter who is today known for surviving the highest known amount of amassed radiation dose in any person. He was secretly part of the Manhattan project, without him actually knowing it. Stevens thought beforehand he had cancer and was injected with a mix of plutonium. He underwent surgery soon after and the claim that he originally thought he had cancer was dismissed by the surgeons. Many of those who took part in the experiments died sometime before Stevens from similar or lesser doses of radiation. On average, he received a scale of 300 portions of radiation a year; the amount permitted to workers is 5.

Effects
His paintbrush allows anyone who touches it to withstand radiation up to sixty times the normal amount, with no immediate or long-term health effects. It also needs to be near something mildly to highly radioactive to activate, so only touching it won’t activate it. The only downside is that after the radiation is back to normal levels, the user thinks that they have some sort of cancer.
