Abstract
A line body portion is subjected to a beam z or parallel beams of electromagnetic radiation having transverse dimensions which are smaller than those of the body portion. The beam is displaced in space in order to sweep the entire volume of the body portion and the attenuation resulting from the passage of the beam through the body is measured in respect of each position of the beam. The mass of the unitary volume of the body portion traversed by the beam is deduced from the measurement, the total mass thereof and the position of its center of gravity being then calculated from a knowledge of the mass of each unitary volume.
