Theoretical analysis of beta- emission from 63-Ni nano-particles in glassy 15-P

Abstract

The energy loss of ${\beta }^{-}$ emission emitting from a 63-Ni source in a phosphorus 15-P scintillation medium is theoretically studied. It has shown the $\beta$ energy spectrum absorption in $15P$ had nearly 100% efficiency for $\le$ 28 keV in 800 μm scintillator thickness. This can eventually lead to the production of light sources using these beta-emitting radiation sources as a low energy source in the near future.
