[Converting] Carbon-14 from nuclear waste to long life battery.
From engadget
Nuclear waste is normally a major environmental headache, but it could soon be a source of clean energy. Scientists have developed a method of turning that waste into batteries using diamond.
From treehugger
"There are no moving parts involved, no emissions generated and no maintenance required, just direct electricity generation," said Professor of Materials Tom Scott. "By encapsulating radioactive material inside diamonds, we turn a long-term problem of nuclear waste into a nuclear-powered battery and a long-term supply of clean energy."
From newatlas
One unexpected example of this is the Bristol team's work on a major source of nuclear waste from Britain's aging Magnox reactors, which are now being decommissioned after over half a century of service. These first generation reactors used graphite blocks as moderators to slow down neutrons to keep the nuclear fission process running, but decades of exposure have left the UK with 95,000 tonnes (104,720 tons) of graphite blocks that are now classed as nuclear waste because the radiation in the reactors changes some of the inert carbon in the blocks into radioactive carbon-14.
Presumably other beta emitters could be wrapped in diamond shells creating a common class of Betavoltaic nuclear batteries. Although the diamond in a diamond seems an elegant technical solution.

Come on man. If you are going to expound on how someone is wrong, the least you could do is google the topic before hitting submit.
A "dirty bomb" is one type of a radiological dispersal device (RDD) that combines conventional explosives, such as dynamite, with radioactive material. The terms dirty bomb and RDD are often used interchangeably in the media. Most RDDs would not release enough radiation to kill people or cause severe illness - the conventional explosive itself would be more harmful to individuals than the radioactive material. However, depending on the situation, an RDD explosion could create fear and panic, contaminate property, and require potentially costly cleanup. Making prompt, accurate information available to the public may prevent the panic sought by terrorists.
A dirty bomb is in no way similar to a nuclear weapon or nuclear bomb. A nuclear bomb creates an explosion that is millions of times more powerful than that of a dirty bomb. The cloud of radiation from a nuclear bomb could spread tens to hundreds of square miles, whereas a dirty bomb’s radiation could be dispersed within a few blocks or miles of the explosion. A dirty bomb is not a “Weapon of Mass Destruction” but a “Weapon of Mass Disruption,” where contamination and anxiety are the terrorists’ major objectives.

And there is no fission or fusion involved, QED.

Do you even know what radioactivity is?
