Why is a mono-energetic radiation source required in X-ray fluorescent

1.	Why is a mono-energetic radiation source required in X-ray fluorescent spectrometer?(a) To provide good sensitivity(b) To provide high accuracy(c) To provide a proper range(d) To reduce unwanted backgroundThis question was posed to me in a national level competition.My doubt is from X-Ray Fluorescent Spectrometer topic in section X-Ray Spectrometers of Analytical Instrumentation
Answer» Correct CHOICE is (d) To reduce unwanted background The best I can EXPLAIN: Mono-energetic radiation source is required in X-ray fluorescent SPECTROMETER to reduce unwanted background. This OCCURS due to the scattering occurring over a broad range of wavelengths.
