Abstract
NUCLEAR research emulsions are sometimes loaded with the stable isotopes of boron or lithium for work on nuclear disintegrations or on neutron counting by the photographic plate technique. Since the usual additions correspond to as much as 16 mgm. lithium or 23 mgm. boron per c.c. of emulsion, and these amounts of isotopes of low natural abundance are costly, the technique is expensive unless the isotope can be readily recovered after plate exposure.
