As defined

"The blur radius is perpendicular to and centered on the shadow's edge
and defines a gradient color transition ranging from the full shadow
color at the radius endpoint inside the shadow to fully transparent at
the endpoint outside it."

and as usually implemented (as a Gaussian or Gaussian-like function),
radius is the more appropriate term. However, the distinction isn't
terribly important, as radius and diameter are (obviously) just a
constant factor apart. The current language would just have to be
tweaked accordingly.
