The Sun is already bombarding everything with trillions and trillions of neutrinos. > In the vicinity of the Earth, about 65 billion (6.5×10^10) solar neutrinos per second pass through every square centimeter perpendicular to the direction of the Sun.[1] Given that each side of the base of the Great Pyramid of Giza is 230.4 meters long, that means it's 5,308,416 cm^2; if the Sun is directly overhead, that means something like: 5,308,416 x 6.5x10^10 / 10^12 = 345,047.04 345,047.04 trillion neutrinos would be passing through the pyramid every second. The problem is detecting them.[2] [1] https://en.wikipedia.org/wiki/Neutrino https://en.wikipedia.org/wiki/Neutrino [2] https://en.wikipedia.org/wiki/Neutrino_detector https://en.wikipedia.org/wiki/Neutrino_detector

The sun is a diffuse emitter. It blankets the entire pyramid in neutrinos. What OP is proposing, I think, is a mobile point emitter and mobile detector. Move these around the pyramid and you can create an array of lines that determine the density through the pyramid on that axis. Rotate the entire setup around the pyramid to generate intersecting lines, and you could build up a map. Of course, the pyramid is also moving around the sun, so you do have a distant point source of neutrinos, but not a very consistent or convenient one. And, of course, the detectors are really difficult. Not exactly something you can hang from a quadcopter and fly around the pyramid... :)
