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 background
This 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
