Answer #1

When used for detection of radiation of UV rays and Visible regions the Photomultuiplier tubes response is the best. So the modification to use this in Xray spectrometer can be done by placing a scintillator. The Scintilator is placed between the incoming photons and the photocathode. The usage of scintilators is to convert higher energy photons to visible photons. And the visible photons can be easily and efficiently mutiplied by the the photomultiplier tubes.

An X-ray machine makes a picture of a broken arm (shown above)by sending high energy photons through an object that is opaque to visible wavelengths and measures the relative intensity of the X-rays that emerge on the other side. Denser substances, such as bone, absorb more photons than less dense substances and thus show up differently. Material Absorption length Air 3.4m Fat 0.052m Water 0.047m Bone 0.017m a.

A Geiger–Muller tube is a type of gas‑filled radiation detector. It can detect particles like X‑rays, alpha particles, and beta rays (electrons). This is useful in quantizing the activity of a radioactive source or determining if an area containing radioactive material is safe to enter. If a Geiger counter is filled with 1 mol1 mol of argon gas at pressure ?=9.760×103 PaP=9.760×103 Pa and temperature ?=26.6 ∘C,T=26.6 ∘C, what is the density ?ρ of the gas in this Geiger tube...
