Biological applications of neutron caputre radiography

Abstract
Although the term “neutron capture radiography” (NCR) is relatively recent, the method and its first application to biology dates to the early fifties (1). Since then, the method has been applied mainly to the detection and imaging of a few stable isotopes undergoing fission or (n,a) or (n,p) reactions with slow neutrons. The principle of the method consists of collecting the particles which are produced in these reactions onto a detector made of a foil of an appropriate substance.
