The WiFi that works with nuclear radiation and the most expensive material in the world: californium-252

The californio is a radioactive chemical element obtained for the first time in the University of California at Berkeley, in 1950, bombarding curium with alpha particles. It is the heaviest element that is produced on Earth, and it is also the most expensive after Antimatter, since obtaining 1 single gram of Californium-252 is worth almost 24 million euros …

What uses does this exotic material have? It can be used to help ignite nuclear reactors, and in the nuclear synthesis of elements of greater mass. And from this year, also to create Wi-Fi signals. Because that’s what this story is about: Of a type of nuclear Wifi that has been created using nuclear radiation to transmit digital data wirelessly instead of electromagnetic waves. No, this is not something that Tony Stark has pulled up his sleeve, but it is true.

Radio waves and mobile phone signals rely on electromagnetic radiation for communication, but in a new breakthrough, Lancaster University Engineers (United Kingdom), in collaboration with the Jožef Stefan Institute (Slovenia), managed to transfer information digitally encoded wirelessly using “fast neutrons” en instead of the usual electromagnetic wave technology.

The researchers measured the spontaneous emission of fast neutrons from californium-252, a radioactive isotope produced in nuclear reactors. Modulated emissions were measured with a detector and recorded on a laptop.. And in the experiment several examples of information were successfully sent: A word, the alphabet and a random number selected blindly.

This digital data is “encoded serially in the neutron field modulation and the output was decoded on a laptop that retrieved the encoded information on the screen ”, achieving what they were looking for: wireless digital information transmission. All transmission tests carried out were 100% satisfactory.

Professor Malcolm Joyce of Lancaster University noted that: “We demonstrate the potential of fast neutron radiation as a means of wireless communication for applications where conventional electromagnetic transmission is not feasible or is inherently limited. “

According to him, fast neutrons have an advantage over conventional electromagnetic waves, which they are weakened considerably when transmitted through materials such as metals.

Possible Uses of Nuclear WiFi: Emergency Scenarios

Since the anti-nuclear energy campaigns of the 70s and 80s, and elements such as nuclear weapons or accidents as sadly iconic as the Chernobyl nuclear plant that are still present, nuclear energy continues to have a bad reputation although today many experts advocate for a mix of renewable and nuclear energy in “Climate-friendly nuclear power plants“, in addition to building new ones to guarantee an electricity supply, and that we do not go through the current crisis in which we live again, with the price of kilowatt / hour triggered by a fuel energy crisis.

Therefore, a WiFi based on radioactive energy makes us wonder about its need. What uses and advantages can nuclear WiFi have that conventional WiFi cannot?

According to Joyce, it can be applied to increase security in certain critical scenarios, “As the relative to the integrity of the containment of the reactors and the vaults and metal bulkheads of the maritime structures “. A radioactive Wi-Fi can be important for “Minimize the number of penetrations made through these metallic structures for communications wiring ”.

Wireless communication mwings effective than conventional

The use of neutrons for the transmission of information through such structures could “nullifies the need for such penetrations and is perhaps also relevant for scenarios where limited transmissions are desirable in difficult circumstances, such as for emergency rescue operations. “

Fast neutrons could also be incorporated into mixed-signal electronic systems to get the signal mixed between electrons and neutrons. This could contribute to the requirement to ensure the integrity of the information transfer.
