My first dev job was a paid internship at Oak Ridge National Laboratory. But I wasn't in the computing division with the supercomputer and the 30-foot 18-screen wall display. In a way, I was doing something more exciting. I was in the Hollifield Radioactive Ion Beam Facility.

That meant that I was working next to a radioactive ray gun that they fired at different targets to try and make new kinds of particles. To refine the beam components, there was a tower with the world's highest voltage Van de Graf generator at 25,000 kilovolts. I got training on how to put on a radiation suit, and was told that if I got locked in the wrong room and red lights began to flash, I had about five seconds to run to the far wall and push the E-stop, before I got irradiated and died slowly over the next five weeks.

But, I was reassured, that never happened. Radiation leaks are rare too (that's why we wore dosimeters). More likely, there would be a leak in the generator tower. To explain why that's bad, that tower wasn't filled with normal air. 25,000 kilovolts would punch through that like nothing, arc against the walls, and we'd lose the electric charge. No, instead, the tower was filled to a few atmospheres of pressure with sulfur hexafluoride gas. You know how helium makes your voice go up? This stuff makes your voice go down. It's heavier than air, and it kills you by displacing and starving your lungs of oxygen.

So, while I was happily coding away on PHP, CSS and the Bash shell, making a log book for all the ion gun settings and targets the scientists used in their experiments, I was keeping an ear out for the oxygen alarm. I had a blast!
