Abstract:
The paper deals with a problem of radiography of a continuous medium of unknown chemical composition.
The medium is subjected to multiple X-raying at different energy levels. The relative errors at incoming
and outgoing radiation are assumed to be known. The paper advances some estimations of absolute
errors at the right side of system of equations describing the process of radiation transfer.
Key words:radiography of a continuous medium, identification the chemical composition of a substance, calculation accuracy.
