What are the differences between X-rays and alpha rays?
X-rays are electromagnetic waves with high energy and penetrate through tissues, used in medical imaging. Alpha rays are particles emitted by radioactive materials, consisting of two protons and two neutrons, and have low penetration power but high ionization ability. In terms of health effects, exposure to X-rays can increase the risk of cancer, while exposure to alpha rays can cause significant damage if internalized.
The frequency of the ray can be calculated using the formula: frequency = speed of light / wavelength. Plugging in the values, we get frequency = 2.998 x 10^8 / 3.10 x 10^14 = 9.67 x 10^5 Hz.
Difference between rotating anode x ray tube and stationary x ray tube?
A rotating anode promotes cooling between exposures by distributing the intense beam from the cathode over the surface of the anode. A rotating anode tube lasts a lot longer than a stationary x-ray tube.
How do X-Rays reveal the structure of atoms within crystals?
When we set up a crystal target and X-ray it, the crystal scatters the X-rays. By examination and noting the angles at which the scattering occurs, and also the varying intensities of the scattered radiation, investigators can figure out the structure of the atoms within that crystal structure. This is called X-ray crystallography, and it relies on what we call X-ray diffraction. The technology has been around for quite a while, having been developed in the early part of the 20th century.
What materials would stop X rays from passing through them?
Materials like lead, concrete, steel, and barium are effective in stopping X-rays from passing through them due to their high density and atomic number. Lead is commonly used in protective garments worn by medical personnel during X-ray procedures.
What are parts of Rotating anode dual focus x-ray tube?
A cathode ray tube will emit electrons boiled off a heater located in the cathode area. As electrons leave the cathode traveling to a more positive potential located at the plate a grid of negative potential can deflect, impede these electrons flow.
1. Medical Uses:
i. Radiography : Radiography is an imaging technique that uses electromagnetic radiation other than visible light, to view the internal structure of a non-uniformly composed and opaque object (i.e. a non-transparent object of varying density and composition) such as the human body.
ii. Computed Tomography: Computed Tomography (CT scanning) is a medical imaging modality where tomographic images or slices of specific areas of the body are obtained from a large series of two-dimensional X-ray images taken in different directions.
iii. Fluroscopy: Fluroscopy is an imaging technique commonly used by physician or radiation therapist to obtain real-time moving images of the internal structures of a patient through the use of a fluoroscope.
iv. Radiotherapy: The use of X-rays as a treatment is known as radiation therapy and is largely used for the management of cancer; it requires higher radiation energies than for imaging alone.
2. X-ray crystallography in which the pattern produced by the diffraction of X-rays through the closely spaced lattice of atoms in a crystal is recorded and then analysed to reveal the nature of that lattice. A related technique, fiber diffraction, was used by Rosalind Franklin to discover the double helical structure ofDNA.
3. Airport security luggage scanners use X-rays for inspecting the interior of luggage for security threats before loading on aircraft. Border control truck scanners use X-rays for inspecting the interior of trucks.
4. X-ray microscopic analysis, which uses electromagnetic radiation in the soft X-ray band to produce images of very small objects.
5. Industrial radiography uses X-rays for inspection of industrial parts, particularly welds.
Components of rotating anode x ray tube?
rotating anode
1)During a operation large shaped disc tungsten anode rotate at speed 3000 t0 9000rpm(resolution per minute).
2)A motive force to rotate the anode is given by induction motor.therefore windings of which is housed outside the tube.
3)a design element help to limit power density delivered on the physical focal spot while making a small effective focal spot.
4)with rotating anode,heat is produced during exposure is spread over the large area of anode.thereby increases the heating loading capacity of the tube and allowing high power level are used as a result which produces the x radiation.
5) by increasing the anode voltage x rays which produces the shortest wavelength this is used to therpeutic.
by decresing the anode current which produces the longest wavelength this is used for diagnostic process.
What wave has a higher frequency microwave of X-ray?
An X-ray is a high frequency (high energy) electromagnetic wave. It is much higher in frequency than any broadcast wave. The only electromagnetic radiation with higher frequency (shorter wavelength) than the X-ray is the gamma ray.
X-Rays have more energy than gamma rays?
This statement is incorrect. Gamma rays have more energy than X-rays. Gamma rays are produced by nuclear reactions and have higher frequencies and energies than X-rays, which are produced by electron transitions within atoms.
materials that emit high-speed particles and energy-containing rays from the interior of their matter.
Who became famous because of his works on soft x-rays?
Casimiro del Rosario became famous on his work about Soft X Rays.
Del Rosario was the co-founder of the Bartol Research Foundation (Franklin Institute) in Philadelphia, an institution which did pioneering researches in physics.
X-rays are not deflected by magnetic fieldWhat does this indicate about yhe nature of rays?
That they have neither a negative or positive charge
Ultraviolet rays are potentially harmful to us due to their?
Ultraviolet rays are potentially harmful to us due to their intensity. This is what is known as the amplitude of the rays from the sun.
What does it mean when a guy tells you that he have x-ray vision?
Either your lying about something and he can see right through your lie OR he is imagining what you look like naked....good luck....
On November 8th, 1895, German scientist Wilhelm Roentgen was conducting experiments in his laboratory on the effects of cathode rays. Specifically he was observing the effect of passing an electrical discharge through gases at a low pressure. While doing so, Roentgen noticed something that earlier studies had not picked up. While passing current through the cathode ray, rays were given off that passed through every day materials such as wood, paper and aluminium. Roentgen further observed that a surface that he had coated with barium platinocyanide and which was placed outside of the cathode discharge tube would give off light despite the fact that it was hidden from the light of the discharge. The conclusions that Roentgen came to were ground breaking: a previously unknown type of radiation had passed through the air and lit up the screen.
Roentgen's discovery was to open up an exciting field for doctors. It was now possible to use this new form of radiation in the study of the human body. Broken bones, for example, could now be looked at by using the rays to see straight through flesh. To underscore the unknown nature of his new discovery, Roentgen decided to call them x-rays.
Roentgen spent the next two months carefully investigating the properties of the new radiation he had discovered. He then made a formal correspondence to the University Physical-Medical Society informing them of his discovery. In 1901 he was to receive the Nobel Prize for his work. It was the crowning achievement of a career that saw him rise from obscurity.
Wilhelm Roentgen was born on March 27, 1845 in Lennop, a small town in Germany's Rhineland. As a young boy, Wilhelm was drawn to nature. He loved to experiment and to pull things apart. His school years, however, were quite troublesome. He was of average academic ability but had a knack for causing trouble. Refusing to bow down to the authority of his teachers, he was eventually expelled from school without any qualifications. This was a problem to young Wilhelm because he had set his sights on an academic career in the sciences.
In his late teens Wilhelm decided to give education a more serious effort. He enrolled at the Poly-Technical Institute in Zurich. Now showing the academic discipline that was earlier lacking, he soon earned a degree in Mechanical Engineering. Having done so, however, he was at somewhat of a loose end. He didn't yet know where he wanted to go with this qualification. It was at this time that Roentgen met the woman who was to be his wife, Anna Ludwig.
xray "spex don't even exist its not possible for there to be any such thing"
Construction rays are imaginary lines used in geometric constructions to extend the direction of a line segment or angle without specifying a particular length. They help in visualizing relationships and intersections between geometric figures during the construction process. Often depicted as straight lines with an arrow at one end, construction rays facilitate the creation of points, angles, and shapes by guiding the drawing of additional elements.
The child had more organic material in her bones, which allows bones to be more flexible, while her grandmother's bones are extensively calcified, with little organic material, and are probably thin due to osteoporosis.
