And you happen to be completely wrong, as usual. Stuff with a short half life is a particularly horrible threat, but you don't want environment contaminated with any of the longer lived stuff either - right out to Iodine-129 with it's 15.7 million year half-life.It is the ones with a short or moderate half life that are problematic for containment. Sr90 (30y) and Co60(5y) being notable examples.That's what I have been saying. Stuff with a half life of a few hundred years is the problem, and a pyramid that works for 5000 years is plenty good enough.
