title: Use of differential tomography in the study of natural processes.
abstract: A few natural processes are studied using the method of differential computer-assisted tomography (DICAT). The detection of an element in any sample either naturally present or given as tracer can be located in a selective manner, which may be used for important medical and nonmedical applications.
