Though with the Tomb, this passage from Wikipedia should be kept in mind:

However, the soil around the dome was found to be more contaminated than its contents, so a breach could not increase the radiation levels by any means. Because the cleaning operation in the 1970s only removed an estimated 0.8 percent of the total transuranic waste in the Enewetak atoll,  the soil and the lagoon water surrounding the structure now contain a higher level of radioactivity than the debris of the dome itself, so even in the event of a total collapse, the radiation dose delivered to the local resident population or marine environment should not change significantly.

This only makes the whole thing more fucked up, but at least the tomb itself isn’t quite as bad as it sounded when I started reading up about it. By virtue of everything else being much worse. Fuck. I think that’s enough internet for today. :'(
