My question for physics PHDs is, at what distance can the radioactive materials in a bomb be detected?

I admit this thesis is a stretch, but if the drones are domestic, what could be their purpose?

The drones have to be domestic, otherwise they wouldn’t be using FAA-Compliant External Lighting and staying clear of US airline flight paths.

Also, it’s hard to imagine any other purpose for the drones than trying to find something radioactive.

Gamma rays are gradually attenuated by air, obey the inverse square law, and can be overwhelmed by background radiation, but gamma rays from enriched materials are easily detected through the lower atmosphere if not well shielded. Well, my brother has a Physics Ph.D. anyway.

Lets say some 'enemy' has told us they've buried nukes in various states and the 'first strike' will come with zero warning. And that one of those nukes in in New Jersey - so we'll know they're telling the truth? And you're question? Wouldn't that depend on the shielding?

Detection of gamma particles depends on shielding, time and distance. The inverse square law applies to distance, by far the best thing you can do is get closer (Half the distance to the source and you get FOUR TIMES the intensity.). In terms of the physics the best improvement you could make is to just get closer.

Chase Hughes has worked for the government and he has an idea what's up. It's YouTube and 22 minutes long so if you don't like videos you can ignore it.

I don’t have a physics PHD, just a BS in nuclear engr. The decay products of U-238 and U-235 (the bomb isotope) are mostly alpha and beta particles which in all likelihood would not even penetrate the casing material of a bomb. Even lower energy gamma rays probably would not penetrate the casing. I don’t know specifics about a “dirty bomb”, but it implies something not clean (in a nuclear sense) and maybe radiation could be detected from that?
