Phys.org  November 10, 2021 An international team of researchers (UK, Slovenia) reports on the configuration and operation of a nuclear instrumentation set-up designed to transmit digitally encoded information using fast neutrons. They measured the spontaneous emission of fast neutrons from californium-252, a radioactive isotope produced in nuclear reactors. Modulated emissions were measured using a detector and recorded. 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. A double-blind test was performed in which a number […]
