Determinacin de la dosis absorbida en haces de fotones y electrones

This second edition contains eight additional pages, summarizing recommended changes resulting from a review of data and procedures presented in the first edition. Otherwise, the report remains unchanged. The report itself represents a step towards a universal code advising users in Secondary Standard Dosimetry Laboratories (SSDLs) and radiation therapy centres throughout the world on how to obtain the absorbed dose from a measurement of exposure or another appropriate quantity. As the numerical result of a physical measurement must be complemented by an assessment of its uncertainty, Appendix A to this Code gives a brief summary of a treatment uncertainties concept by A. Allisy and J.W. Mller from the Bureau International des Poids et Mesures (BIPM).
