title: [Determination of the error of calculation of the effective energy of combined X-ray beam].
abstract: A formula for assessing the error of calculation of the effective energy of combined X-ray beam is derived. Maximal error of calculation of the effective energy of combined X-ray beam is found to be (4% for anode voltage of 40-150 kV and aluminum filter thickness of 2-45 mm.
