researchers propose that c-14 gas obtained by heating the radioactive graphite waste will be collected and subjected to low pressure and elevated temperature, to produce a man-made diamond by a process known as chemical vapor deposition. a diamond made of radioactive c-14 will also be radioactive, and its radioactivity may allow it to act as a betavoltaic device, generating small electrical currents. for practical and safe use it would be enclosed inside a non-radioactive man-made diamond (made from c-12). more diamond will make more current, even with the same radioactivity, and the outer diamond will shield the user from the radiation emitted by the inner diamond.
