SI units in radiology and radiation measurement

Abstract The International System of Units (SI) is a practical system of units of measurement suitable for adoption by all signatories to the Metre Convention. While the general implementation of SI means new difficulties in the future use of the special radiological units, the units curie, rontgen, and rad can all be exactly expressed in SI units. A table shows the conversion factors which indicate that the SI units imply substantial changes in the numerical values of the actual quantities. It may be that some of the problems involved may be solved by introducing new names for the derived SI units.
