Technically yes, but practically no for the first question. Properly stored nuclear waste has very minimal radiation leakage.

As for the second, it’s complicated. The actual amount of radioactive waste is less than 10,000 cubic meters. There’s quite a bit more than that of just water that has become toxic due to radiation, but the storage requirements of that are much lower. Here’s a rough infographic: https://www.visualcapitalist.com/visualizing-all-the-nuclear-waste-in-the-world/

Also, while The low level waste would still fit in a single square mile if you were restricted to that, using natural caves is a lot cheaper and easier than building tanks, so it’s not exactly a realistic solution.

Breathing is the no risk, no effort, (relatively) low reward option. The only time you’ll stop making money is if you’re dead, and you’re still making 350,000 a year.

All nuclear waste ever produced could be safely stored in less than a square mile (Plus a radius around that to prevent idiots tampering with it). The safety issues of it are greatly over exaggerated most of the time. The problem with that, is that storing nuclear waste safely is relatively (though not extremely) expensive.

Including all nuclear power plant disasters, it still has far fewer deaths per gigawatt hour compared to everything except large scale solar installations (not personal rooftop solar, which is much higher due to falls). It’s the money, not the safety, that’s the problem.

On one hand, breathing is the safe route that doesn’t stop until you’re dead, and even at the lower bound average of a random internet search (12 breaths per minute), still provides over $850 a day.

On the other, if walking earned you money, you’d almost certainly become healthier and live longer. Plus, unless you had an accident, you’ll be able to put away enough money to live off the interest forever and only a few years of normal walking.
