Even the Fallout wikia page on Vault 34 mentions the potential for a toxic save, ie one where you're screwed if you stay or even if you try to leave, because the save dumped you past the point of no return.
But yeah. Short of cheating, the only thing to do is start over, and learn the lesson about multiple saves the hard way. If you're on PC, you have a way out. I don't think that's the case with the PS3 or 360.
I found Vault 34 quite by accident my first trip through. I saw the radioactive waste by the mountain entrance, and all the waste sitting in the tunnels to the door, and I put on my radiation suit that I had scavenged. I was still getting 1RAD/sec or so. I explored a bit, before realizing I wasn't going to have enough Rad-X or Rad-Away to survive, and I was having a tough time killing the Overseer and the flood of vault security, so I high tailed it out of there, making a mental note to stock up on more radiation protection.
As for saving, ALWAYS multi-save. At least once before entering a vault, or a building, and then at safe moments while inside the building. And with autosave, that ends up with 3 saves. Might be redundant and unnecessary, but I don't have to necessarily concern myself with toxic saves.
