Evaluation of the uncertainties in KAP-meter calibrations

This report was prepared in order to give more details to the uncertainty evaluation of the Kerma area product meter calibration procedure described in the paper: Larsson J P Persliden J Sandborg S and Alm Carlsson G 1996 Transmission ionization chambers for measurements of air collision kerma integrated over beam area. Factors limiting the accuracy of calibration. Phys. Med. Biol. 41 2381-2398. Figures and equations referred to in this report will be found in the paperabove. For convenience, however, the equations in the paper that are used in the uncertainty analysis are retyped on the next two sides, see text in section 2.7. in the paper for further details. The numbering of the equations are kept as in the paper
