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)
