How much more dangerous would that be compared to space normally?

[marcosdumay]

Space usually stops being dangerous once you get into some atmosphere. Nuclear waste doesn't.

[itworkslikethat]

Space is very irradiated, and direct sunlight is radiation itself. Anything you add there will be a drop in the ocean. Atmosphere is not sufficient to resolve space radiation, you need a magnetosphere.

[marcosdumay]

You don't take sunlight inside with you when you enter some place.

You take neutron radiation (well, its consequences), but that is pretty much non-existent when compared to nuclear waste.
