The various protective actions are linked to levels of concern (called "bands") that are defined in terms of multiples and submultiples
of the natural background radiation dose (ICRP 2001).
Finally, there are the SI prefixes for forming multiples and submultiples
of coherent units in order to express values of quantities significantly larger or smaller than the units.
First we note that the throughput of the monochromator could be characterized as having a main peak at the wavelength of interest, [lambda], generally smaller, higher order peaks at submultiples
[lambda]/n, and even smaller broad-band scatter that we shall label S[lambda]([lambda]').
This is followed by dissemination to multiples and submultiples
of the kilogram covering the range from 1 mg to 27 200 kg.
