Gamma-ray shielding against bursters

Earth's atmosphere is pretty good at stopping the gamma rays from a burster. Further, the primary effect is to crash the ozone layer, not flash-fry the surface with lethal rads.

I'm not sure how a gas giant's hydrogen-helium atmosphere compares, but since enough mass should block energetic photons like anything else I'd guess those gases are on par with Earth for a given areal mass of atmosphere. Of course, a hydrogen-helium atmosphere has about 1/10th the molecular mass of Earth's atmosphere.

Therefore, somewhere in the vicinity of 5 to 10 atmospheres pressure in a gas giant should provide adequate shielding. On some gas giants, that's a quite comfortable level for humans. Bubblehabs, never mind crashcaches, would be fine.
