Can anyone tell me why I am getting noise in my images at ISO 200?

Below is a 100% , non-adjusted, crop of an image taken from a raw file which demonstrates the noise which I think shouldn't be so pronounced in the off-focus shadows.

The full image can be seen here

EXIF data is here:

Camera Model:.............Nikon D300
Pixel Size:....................407 x 612
Aperture:.....................f/22
Shutter Speed:.............1/60
Exposure Bias:..............0ev
Focal Length (35mm):...24.0mm
Focal Length:...............16.0mm
ISO Speed Rating:........ISO 200
Lens Minimum (mm):....16.0mm
Max Lens Aperture:.......3.7
Len Maximum (mm):.....85.0mm
Lens Model:..................16.0-85.0 mm f/3.5-5.6

I couldn't export the histogram but there is no clipping of highlights or shadows in the image (in case that's in any way useful to know)
