This would be interesting of it would work. Even though I did not grasp the plot properly, I assume it takes care of interaction of nucleus that might happen with other stuff, say neutrinos and dark matter would have it's own characteristic signature. I guess that's what you meant?

On a slightly unrelated note this question came to my mind. Do we even know that dark matter flows through earth or earth passes through some region full of dark matter? How would we ensure that dark matter interaction would occur here on earth?
