The KamLAND detector in Japan can detect anti-neutrinos generated by the decay of uranium and thorium-the two elements responsible for most of the radioactive heating of the Earth.

日本的KamLAND探测器可以检测衰变的铀和钍产生的反中微子，这两种元素产生了地球放射热量中的很大部分。

Later this year, Fermilab, outside of Chicago, will start sending a beam of neutrinos 500 miles through the earth to the NOvA detector near the Canadian border.

ENGADGET: NOvA neutrino detector captures cosmic rays in 3D, aims to unlock the mysteries of the universe

As luck would have it, a project called NOvA, which should start collecting data in the spring of 2013, will send neutrinos through the Earth's crust from Batavia to an underground detector 810km away in Minnesota.
