Also on point, if they have forgotten about the concept of nuclear radiation then discovering a nuclear waste dump will be a massive boon and cause for celebration. When we zoom out enough to see entire civilisations at once, a few people dying just isn't an issue; it is routine. We try our best to keep everyone healthy, but at the end of the day the benefits of progress outway handfuls of dead astronauts, scientists, explorers and early colonists.

We don't sit around moping that Marie Curie & co died doing research, everyone involved gets recognised for helping to usher in a new age of scientific progress.
