Last night I was watching the latest Alien: Covenant movie, where the crew and colonist are brought out of cryosleep to repair damages to the ship caused by a "neutrino blast". This didn't sit well with me, so I did some searching and thought I'd share what I found:

Lethal Neutrinos: https://what-if.xkcd.com/73/

Which of the following would be brighter, in terms of the amount of energy delivered to your retina:

1. A supernova, seen from as far away as the Sun is from the Earth, or

2. The detonation of a hydrogen bomb pressed against your eyeball?

... and humans are much more fragile than spacecraft components.

4 Sv can kill a human, while most electronics will survive that easily. Purely structural material will survive 1 MSv without notable damage, and even some electronic components can survive that.

If there is damage to the ship, the humans are dead.
