I’ve heard (in an older YouTube video that I can’t find anymore) that this is not as bad as it sounds. Radiation limits are, supposedly, ridiculously low right now because of public perceptions/fears of times past. As in, they are uselessly low, way below what people in many occupations regularly experience with no measurable ill effects, but the limits incur large costs and complications.

Take this with a lot of salt though, since I have nothing to back up my vague memories of this.
