X-Ray

X-rays, gamma rays, radio waves, and visible light are forms of electromagnetic radiation. Gamma rays are highest in energy compared to other electromagnetic radiations. Radio waves are least in energy in the whole electromagnetic spectrum.

An x-ray of the breast is called a mammogram.

This was World War 1, as Marie Curie wasn't alive during World War 2.

yes, we can do it by using NI VISION LAB VIEW SOFTWARE.

X-Ray voltage means voltage which is applied across anode & cathode, this is of very high voltage (in KV). This causes a high electric field for the moving of electrons emitted from cathode to anode. One more voltage wrt X-ray tube is filament voltage. Filament voltage with some appropriate current is applied to filament for the emitting of electrons. This current is proportional to the intensity of X-ray radiation generated from the tube. More current through the filament causes permanent damage of filament.

As CT can identify structures that have physical density differences less than 1%. On the other hand X ray films can identify structures having density difference of about 10%.

Barium solutions (which contain barium ions) are toxic. As regards drinking them, it's a very bad idea. But as the question is being asked in conjunction with X-ray and Medical Technologies categories, the query may be directed at the use of barium as a contrast agent. Barium sulfate, which is used for contrast in some imaging, is insoluble in water, which is the way it is given, and that means no barium ions. That allows its use without actually poisoning a patient. The compound is, however, something that the body doesn't like, and it can leave a patient with some gastrointestinal issues after it is taken. These issues are not generally severe, and that makes the use of barium sulfate relatively safe for use as prescribed.

X-ray diffraction is the investigative use of X-rays to discover the internal structure of a number of different things. The basic approach is to set up a target material and direct a beam of X-rays at it. By looking at the pattern of the scattered X-rays noting the scattering angles and their relative intensities, observers can come to informed conclusions about the internal structure of that target material. It must be noted that the manner in which X-rays scatter can vary a good deal, and X-ray diffraction technology has become a broad field with diverging and complex investigative techniques. Even so, the fundamentals remain the same.

True X rays are not produced by elements- they are produced by an electric current and an X ray tube. However, radioactive elements such as Cobalt and Uranium can be used to produce a radiographic image, and are commonly used to inspect welds in metals, However, they use gamma rays and not X rays.

Liquid mercury has not a spectrum of absorption in visible light; diffraction is not used for chemical analysis.

You are talking about an X-ray negative . . . it is exactly the same as a photograph negative, but instead of using light to expose the negative film like an everyday camera, it uses an X-ray machine to expose the negative film. In either case, you develop the film with, well, developer, rinse it to stop the developer, then bathe it in a bath of acetic acid (like vinegar) to make the image not be sensitive to xrays (or light) anymore.

The intensity of the x-ray can be increased by the voltage going to the cathode which will increase the amount of electrons being given off through the vacuum and hitting the tungsten target which means more electrons hitting the target so more x-ray radiation being given off. You can also change how fine the beam is because if you have the beam of electrons focused on one area then the increase of the electrons hitting that one area will cause the increase in x-rays being given off instead of them being spread out over a large area.

Not beryllium sulphate is used as contrast substance in x-ray radiology but barium sulphate; barium is a heavy metal and strongly absorb x-rays.

There are plenty of celestial bodies that emit xrays - while others scatter, reflect, or alter the energy of electromagnetic radiation into the x-ray range. Sources that emit x-rays include pulsars or neutron stars, the accretion disks of black holes, stars - particularly ones with certain types of companions, stellar remnants such as from supernovae, entire galaxies (with and without active nuclei) and to some extent, even the universe as a whole; though some of this is generally attributed to mechanisms which heat gas. There are even x-ray sources within the solar system, including the Moon, since not all of its observed x-ray emission is simply reflected from the Sun.

WW2 x ray machine was used to help people who were shouting mummy then get shot for being anoying

No, you can't. The high energy photons pass through you, and will do some damage to the tissues of your body because they are ionizing radiation, but you will not be able to feel it.

electromagnetic radiation

The exam is performed in the radiology department. The night before the test, patients swallow six tablets (one at a time) that contain the contrast (x-ray dye). The following day at the hospital, the radiologist examines the gallbladder with a fluoro.

The field is called "electromagnetic radiation" or "EMR." It encompasses the study of all types of electromagnetic radiation, including visible light, x-rays, gamma rays, and ultraviolet radiation.

depends on what they invent and how successful they are.. back then they got 10g's like aleander grahm bell when he invented the telephone.

Over 90% of inventors never make a penny because of their inventions, they usually make their money on their "day job", which may not be much at all.

If by RMS voltages you mean what is the RMS voltage of the power source voltage to the device proper it might be 120 volts AC like right out of the wall where you plug it in. That 120 VAC is an RMS voltage. That's the way we measure AC voltages like those wired into residential and commercial settings. Picture an AC sine wave. For a sine wave that is 120 volts RMS, its peak voltage will be right at about 170 volts. Volts RMS is the so-called DC equivalent voltage. The RMS voltage for a larger X-ray machine could be 220 VAC or 440 VAC, too, as higher power units are available. These units can be fixed or "permanent" in a medical setting or in an industrial plant, and can take advantage of higher electrical bus voltages. The X-ray tube itself runs on a DC voltage. A DC voltage doesn't usually have the idea of RMS associated with it. The voltage is "fixed" and not changing over time like it does in an AC source. Modern X-ray tubes can have operating voltages that range from 10 kV to 300 kV applied to accelerate the electrons before slamming them into an anode target.
