Answers are the professional opinions of the expert responding to each question; they do not necessarily represent the position of the Health Physics Society. Metals are solid materials in which some electrons are not strongly bound to a single nucleus, but instead form an electron cloud dispersed throughout the whole object.

If not, it will hit an electron and kick it away at high speed. Since MRI uses a very strong magnet, metal on or inside the body may be affected, so be sure to tell your scheduler and technologist about any device, metal, or shrapnel in your body, and they will determine if it is safe for you to proceed with the MRI exam.

Your implant or device may come with a special information card that you should bring to your appointment and show to the technologist. Artificial heart valves Implanted drug infusion ports or pumps Artificial limbs or metallic joint prostheses Metal pins, screws, plates, stents, or surgical staples Some IUD's These are but a few of the implants that require detailed information to determine MRI compatibility.

Please inform your physician, imaging scheduler and technologist of anything within or on your body that was not present at birth. Dental fillings and braces usually are not affected by the magnetic field, but they may distort images taken of the head or face.

So in other words the ray will show metal before bones! You can 't have metal on when taking a Ray because it has a magnetic field & will distort the results.

According to Steve Gilman, Fortress Technology president, ten to fifteen years ago most metal detectors were end-of-line. Now, he says, processors are placing about 30% upstream to catch contaminants before they wind up in smaller pieces of product.

The signals and the data they create can be recorded to generate a pictorial representation of the whole hour’s or day’s worth of production-whatever the time base is. This trend information can be linked with products that pass through the detector and used as a powerful diagnostic tool that allows users to look into their process and ascertain what is happening in the system.

Providing machines with multiple, available frequencies lets processors tune the detector to their specific application. Through several years of experience, Loop has found that with conductive products such as cheese, operating at a frequency of 300 kHz will give good results.

The quantum yield of X-rays increases with atomic number; light elements give mostly Auger electrons and heavy elements mostly X-rays. Thus glass, containing mainly Si and O, will give a lower yield of X-rays than a heavier metal, such as iron or tungsten.Thus, much I know from my acquaintance with SEM.

The other is via bremsstrahlung process where the electrons generate the EM radiation because they are being slowed down. This is where it is relevant to the OP's question, i.e. why is it more efficient to generate x -rays with a metal anode.First, obviously, it is because one can efficiently set a higher potential for a metal than for an insulator like glass.
