I’m standing 20 feet from the brightly glowing core of a laboratory nuclear test reactor the size of a van, and the Geiger counter next to me is going nuts. But no worries, I’m told. The light, visible on a nearby monitor hooked up to a camera inside the reactor, is not from nuclear fission; it is harmless emission from electrons zipping out of the core and shedding their energy into the water that surrounds it. And the stream of particles eliciting the shriek from the Geiger counter is not from the reactor at all. Just for a giggle, the reactor manager has placed the detector next to a Fiestaware cup, which happens to be one of many everyday items that are mildly radioactive. He keeps it on hand to tease visitors. I am actually getting less radiation here than I would on the beach or in an airplane.
You’ll have to forgive the folks at Oregon State University’s Radiation Center for having a little fun. Nuclear power fell into a long funk after the partial core meltdown at the Three Mile Island reactor in Pennsylvania in 1979. All new nuclear plant construction in the United States came to a halt, and before the industry could recover, the 1986 reactor breach at the Chernobyl nuclear plant in Ukraine seemed to seal the fate of nuclear power in this country. Now the technology is hot again—this time in a good way—because it produces virtually no carbon emissions and it backs us away from the turbulent politics and economics of oil.
