The neutron radiographic thermal analysis (NRTA)

Abstract The principle of the new method is based on controlled heating of a sample placed in a neutron beam. The intensity of the neutron beam passing through the sample may be varied due to possible physical or chemical changes caused by heating. A neutronographic image of the heated sample can be continuously observed. For kinetics studies one may take image photographs by proper temperature and time Points. The method is exceedingly convenient for evaluation of processes connected with changes in content of hydrogen compounds, especially of water. The NRTA has been applied to a topographic analysis of bounded hydrogen distribution changes throughout a cylindriform block of kaolinite.
