Forsmark Travel Guide
Now this is extreme tourism. We've discovered that tours to a nuclear plant in Sweden are all the rage for travelers in Scandinavia. Every year about 15,000 visitors stroll through the Forsmark Nuclear Power Plant on the remote Baltic coast of Sweden.
Yes, this is the same place that has had a couple emergency shut-down scares in the past few years, but the tourists don't care. They traipse around the site with a dosimeter to measure radiation exposure. If your device fails to pick up any radiation readings while you're there (and that's what normally happens), an electronic voice announces "You're clean" as you leave.
When you think about all the tourists who swing by Chernobyl in Ukraine (there are heaps of them), perhaps visiting a place like Forsmark is actually a sensible kind of trip to make. That is, if you're into dangerous nuclear power plants.
