Possible to survive gamma ray burst?

Death, thou shalt die

Gamma ray radiation exposure is subject to distance and intensity. A person in a mine would usually be safe but it depends on the intensity and what the mine is surrounded by. Gamma radiation is used in hospital Gamma knives where they converge rays from a gamma source on a point inside the brain. It destroys the tissue that it is aimed at (hopefully the cancer) and leaves the surrounds tissue relatively intact. You concentrate the radiation from different directions in a 3D matrix - to get a build up fatal to the tissue at the point of intersection. Gamma waves drop off rapidly with distance.

Neutrinos are the radiation that nothing stops. Fortunately there are few encounters with this type particle.

One place that neutrinos would be fatal is near to a supernova.

When I wanted to describe the (future) explosion of the Wolf-Rayet star Regor I imagined that observers could hide behind the companion star, being protected (or so I thought) by the bulk of a star ten times the mass of the Sun; however, even with this mass shielding them, and with a separation of 1.2 AU between the stars, the dose of neutrinos would be instantly fatal. You have to travel to the second companion, 15000 AU away, to reach survivable levels of this ghostly radiation.

Gravitational waves are even more penetrating than neutrinos. But of course, this also means that they’re even less dangerous. If something easily passes through shielding without interactions, that means it’ll also easily pass through you without interactions.

Of course, it’s never actually entirely “without interactions”. In the real world, it’s “with very very few interactions”, which means that, given enough of them, you’ll still get some, as eburacum45 points out.
