Honestly, the military would probably come after you first. Or maybe an oil company? Frankly because if you could detect neutrinos at that resolution you would be able to produce a really good mapping of... just about anything. From the inside of the Earth to the inside of a secret military facility on the opposite side of the planet. Not to mention you've also invented a communication device that is essentially unjammable[0].
Sufficient to say that you'd be very popular, but in probably the least fun way possible.
