Hi Josh, the half-life of Uranium-235 is 700 million years and below the concrete there is a lot of very contaminated soil, which has come in contact with nuclear fallout from numerous nuclear tests (weapons-grade U-235 and U-238). Despite the enormous size of the concrete dome, it is not very thick and won't stop all the radioactive particles, especially the gamma type. So bringing a Geiger counter when trekking in that area would be a good idea indeed. Looking at the picture above, there are however people walking on top of the dome, so the radiation is probably not fatal. :)
