[ RadSafe ] SI units

[FISHER Spencer -NUCLEAR]

Last November I attended three Categorical Courses in Diagnostic
Radiology Physics at the RSNA/AAPM meeting in Chicago.  The courses were
on X-Ray Imaging and Radiation Dose Optimization.  All the units given
in the course were in SI units.  All of the speakers were Americans, and
all of the examples shown were US exampled.

In addition, almost all of the machines that display the Dose Area
Product do so in cGy and rad, since 1 cGy = 1 rad.  This includes many
of the machines that are manufactured in the USA.  The x-ray companies
are multinational and want a product that can be used anywhere.
