Nuclear WiFi
Researchers from Lancaster University have developed a new version of Wi-Fi data transmission technology, where the radioactive isotope californium-252 is used as a signal source. It generates radiation in the form of fast neutrons, which can be sent from the transmitter to the receiver instead of radio waves. Scientists managed to influence this radiation by encoding and transmitting useful information with its help.
The technology was nicknamed "cursed" by analogy with fictional analogues from the Fallout universe, where ignorance of people in the era of "atomic romanticism" is played out. Then, due to lack of knowledge and experience, they greatly underestimated the danger of radiation and seriously believed that compact atomic devices would radically change life. Modern scientists are more pragmatic and therefore do not even consider the option of creating a commercial version of "nuclear Wi-Fi". This type of communication will involve constant risk, but it has a significant advantage – unlike a radio signal, fast neutrons have excellent permeability. And therefore, with their help, you can transmit a signal through a powerful barrier, like the wall of a bunker or the hull of a submarine, without damaging it itself. In emergency situations, when cable communication is not possible, a fast neutron wireless connection can be very useful.
