Howling:How is Captain Jack Immune to Stet Radiation?

In the show, it's been established that Jack is just a normal human, but the time vortex always brings him back. This means he can die, but is always resurrected once the body has been restored. Why then, did Stet radiation not kill him? I haven't seen "Utopia" for a few years but I don't recall there being an explantion. It's possible that his race is immune to radiation, or that the radiation creates a small injury before finishing the body off which he could have healed, or perhaps that radiation has a weird effect on time energy. However I'm still surprised there was no explanation. Was there something I missed? I'd appreciate it if someone who has seen the episode recently could explain it. 94.72.237.220talk to me 17:09, January 20, 2012 (UTC)

They didn't really give an explanation other than that he couldn't die. It can't be that his race is immune to radiation because he is, mostly, human. Most likely, he was able to heal before the radiation disintegrate him. He was shown to be in some pain due to the radiation.Icecreamdif talk to me 18:20, January 20, 2012 (UTC)

I have a new theory that might work out. Jack's first death was being shot by a Dalek gunstick. Since the gunstick appears to give off a radioactive effect, this might explain why he is immune to it. In "Journey's End" he was able to recover from a gunstick blast almost instantly, so this would make sense. The time energy will have a different way of dealing with death by gunstick because that was his original death - it had to use more power to bring him back from that death because he had been dead for ten minutes. 94.72.237.220talk to me 19:04, January 20, 2012 (UTC)

The Dalek guns can't use stet radiation though, because they don't vaporize their victims' bodies. The main problem with the stet radiation isn't that Jack recovered too fast, but that he didn't die at all. Icecreamdif talk to me 19:32, January 20, 2012 (UTC)
