Nuclear radiation used to transmit digital data wirelessly

Engineers have successfully transferred digitally encoded information wirelessly using nuclear radiation instead of conventional technology. The researchers measured the spontaneous emission of fast neutrons from californium-252, a radioactive isotope produced in nuclear reactors. Several examples of information, i.e., a word, the alphabet and a random number selected blindly, were encoded serially into the modulation of the neutron field and the output decoded on a laptop which recovered the encoded information on screen. Fast neutrons have an advantage over conventional electromagnetic waves, which are significantly weakened by transmission through materials including metals.
