Nickel is also an micronutritient essential for proper functioning of the human body, as it increases hormonal activity and is involved in lipid metabolism. Radioactive isotopes used in nuclear batteries have half-lives ranging from tens to hundreds of years, so their power output remains nearly constant for a very long time. These particles have a half-life of 100.1 years. In 1953, Paul Rappaport proposed the use of semiconducting materials to convert the energy of beta decay into electricity. When a gas is passed through the ECD, some electrons of certain molecules which pass through the detector are captured and the current being measured reduces, which results in a positive peak being recorded.

Unfortunately, nickel isotopes appear to have been heterogeneously distributed in the early Solar System. So, for U-235 for example, when it decays via -decay, a Geiger counter will only detect it if there is no 'window' on the detector as alpha particles cannot penetrate through solid matter very far. Conventional mechanical and ionic techniques of diamond thinning were not suitable for this task. Since there are two protons, the charge of an alpha ^{13}_{7} N to, The atom undergoes beta particle emission. It is proposed to be used for miniature betavoltaic generators for pacemakers.
