FIELD: investigating or analyzing materials.
SUBSTANCE: method comprises introducing contrast agent into the object to be analyzed, irradiating the object by ionizing radiation, and recording spatial distribution of the secondary radiation generated when the object is affected by the ionizing radiation. The contrast agent is made of the water solution of zinc chloride or zinc bromide.
EFFECT: decreased toxicity.
