title: [A method of calibrating the aluminum wedge for x-ray photometric research in occupational pathology].
abstract: Calibration procedure of aluminum wedge by optical density gradient of its X-ray image compared to density of standard bone wedge was described for X-ray photometric studies. Calibration of standard aluminum provided the opportunity to determine skeleton mineralization not only by wedge depth but also by units of mineral salt concentrations.
