It used to be very flammable back in the 1930's and 40's and actually caused some fires in hospitals. Now they're much more resistant, but might be somewhat flammable. It might not be good to burn off the chemicals that are in the film though.
What is heterogeneous X-ray beam?
Based of my understanding, a HETEROgenous X-ray beam would have radiation consisting of different frequencies, various energies, or a variety of particles A HETERO BEAM WILL BE OF THE same STRENGTHS due to The filter ( FDA/MQSA required)
Is a plain X-ray suitable for diagnosing a dislocation?
In most cases an x-ray would not be required but it may certainly be used.
Is the phrase a x-ray correct or an x-ray?
You would say "an x ray," Because it is pronounced "Ex Ray."
Phonetically, an x-ray is the correct way. Since x-ray is a special case and sounds like it has the "e" vowel at the beginning, an would be the appropriate article. This avoids a glottal stop when speaking.
Here is a Wikipedia article regarding this question:wikipedia.org/wiki/English_articles#Discrimination_between_a_and_an
What are the x rays of bone survey series?
PA chest x-ray, AP and Lateral skull, AP and lateral cervical spine, AP and Lateral thoraxic spine, AP and lateral lumbar spine, AP Pelvis, AP Humerus Rt and Lt, AP Femurs RT and Lt. and additionally any long bones where the patient may be experinecing pain.
How do you recover silver from an X-ray?
Silver is actually recovered from the spent chemicals left after the film has been processed. Silver is used in the production of film, and when the film is developed, that silver can be (and is) recovered.
How do astronomers use x-rays?
X-rays are electromagnetic radiation which is well above the frequencies of visible light. Their energies give astronomers an indication of the physical conditions causing them. In exactly the same way as a particular wavelength (/frequency) of light informs of a particular energy transition in an atom. This is a direct measure of the chemical make-up in that distant light. From the energy of the x-ray we may infer particular physical processes taking place.
Can you see a penis in an x-ray?
Yes. For example, the X-rays used by TSA used to create images that appeared as "virtual nudes." But in May 2013, TSA announced that it eliminated all invasive X-ray machines. Now, the X-ray machines create a generic outline of a person, showing a colored box where the potential weapon could be.
Using what incidence optics the Chandra is the x ray equivalent of the HST?
The Chandra X-ray Observatory primarily uses grazing incidence optics to focus X-rays, similar to how the Hubble Space Telescope (HST) utilizes reflective optics to capture visible light. In grazing incidence optics, X-rays are reflected off specially designed mirrors at very shallow angles, allowing them to be focused effectively. This technique is essential because X-rays penetrate most materials and cannot be focused using conventional lenses. Therefore, Chandra is considered the X-ray equivalent of HST, serving a similar purpose in its respective wavelength range.
Which is more dangerous uv or x-rays?
X-rays are more dangerous as they have a higher energy than UV radiation. The higher the energy, the more potential for DNA damage.
How many megabytes does a chest x ray require?
depends on imaging system. they range from 5 to 10 megapixels each. each megapixel requires 1.5 megabytes of storage because of 12 bit grayscale.
So... best equipment produces 10 megapixel image requiring 15 megabytes of information to be stored. The images are stored in jpeg2000 format which cuts the size in half using nonlossy compression.
So summary it takes up to 7.5 megabytes of space on the hospital hard drive to store one xray.
Why is lead used in the walls of x ray rooms?
lead can stop the radiation from getting outside the room lead can stop the radiation from getting outside the room
When does Thermionic emission occur during x-ray production?
thermionic emission occurs when the filaments are heated to a certain degree, causing the electrons to boil off and form a space charge or electron cloud.
What medical inventions and procedures are directly attributable to the invention of the x-ray?
1-all general xrays,chest,extremities,spine,etc
2-IVPs,voiding cystograms,mylelograms, all special prodedures
3-tomography, which helped the invention of CT then came the MRI
4-All MRI, that is No radiation,a magnet, but was invented using same principles of CT
5-mammography
6-all operating room radiography Carms
7-all portable radiography
8-bone density that uses little radiation
9-dental radiography
10-nuclear medicine all, including spect scanning
The list goes on RT 45 years
Discovery of x-raysHand mit Ringen: print of Wilhelm Röntgen's first "medical" x-ray, of his wife's hand, taken on 22 December 1895 and presented to Professor Ludwig Zehnder of the Physik Institut, University of Freiburg, on 1 January 1896[4][5]An X-ray picture (radiograph) taken by Röntgen of Albert von Kölliker's hand at a public lecture on 23 January 1896[6]
During 1895 Röntgen was investigating the external effects from the various types of vacuum tube equipment-apparatus from Heinrich Hertz, Johann Hittorf, William Crookes, Nikola Tesla and Philipp von Lenard-when an electrical discharge is passed through them.[7] In early November he was repeating an experiment with one of Lenard's tubes in which a thin aluminum window had been added to permit the cathode rays to exit the tube but a cardboard covering was added to protect the aluminum from damage by the strong electrostatic field that is necessary to produce the cathode rays. He knew the cardboard covering prevented light from escaping, yet Röntgen observed that the invisible cathode rays caused a fluorescent effect on a small cardboard screen painted with barium platinocyanide when it was placed close to the aluminum window. It occurred to Röntgen that the Hittorf-Crookes tube, which had a much thicker glass wall than the Lenard tube, might also cause this fluorescent effect.
In the late afternoon of 8 November 1895, Röntgen determined to test his idea. He carefully constructed a black cardboard covering similar to the one he had used on the Lenard tube. He covered the Hittorf-Crookes tube with the cardboard and attached electrodes to a Ruhmkorff coil to generate an electrostatic charge. Before setting up the barium platinocyanide screen to test his idea, Röntgen darkened the room to test the opacity of his cardboard cover. As he passed the Ruhmkorff coil charge through the tube, he determined that the cover was light-tight and turned to prepare the next step of the experiment. It was at this point that Röntgen noticed a faint shimmering from a bench a meter away from the tube. To be sure, he tried several more discharges and saw the same shimmering each time. Striking a match, he discovered the shimmering had come from the location of the barium platinocyanide screen he had been intending to use next.
Röntgen speculated that a new kind of ray might be responsible. 8 November was a Friday, so he took advantage of the weekend to repeat his experiments and make his first notes. In the following weeks he ate and slept in his laboratory as he investigated many properties of the new rays he temporarily termed X-rays, using the mathematical designation for something unknown. Although the new rays would eventually come to bear his name in many languages where they became known as Röntgen Rays, he always preferred the term X-rays. Nearly two weeks after his discovery, he took the very first picture using x-rays of his wife's hand, Anna Bertha. When she saw her skeleton she exclaimed "I have seen my death!"
The idea that Röntgen happened to notice the barium platinocyanide screen misrepresents his investigative powers; he had planned to use the screen in the next step of his experiment and would therefore have made the discovery a few moments later.
At one point while he was investigating the ability of various materials to stop the rays, Röntgen brought a small piece of lead into position while a discharge was occurring. Röntgen thus saw the first radiographic image, his own flickering ghostly skeleton on the barium platinocyanide screen. He later reported that it was at this point that he determined to continue his experiments in secrecy, because he feared for his professional reputation if his observations were in error.
Röntgen's original paper, "On A New Kind Of Rays" (Über eine neue Art von Strahlen), was published 50 days later on 28 December 1895. On 5 January 1896, an Austrian newspaper reported Röntgen's discovery of a new type of radiation. Röntgen was awarded an honorary Doctor of Medicine degree from the University of Würzburg after his discovery. He published a total of 3 papers on X-rays between 1895 and 1897. Today, Röntgen is considered the father of diagnostic radiology, the medical specialty which uses imaging to diagnose disease.
What is the radiation source for x-ray waves?
X-rays are produced by the electric field of an atom. This is usually discussed in terms of characteristic X-radiation and bremsstrahlung. Most X-rays in hospital X-ray kit are the latter (the exception is mammography) . Electrons are fired from an electron gun at a tungsten target. When the electrons pass close to a tungsten atom they interact with electric field. This deflects the incoming electrons, slowing them down, reducing their energy. The excess energy is given of as X-rays.
What does X ray consist of and how harm full is it?
An x-ray is basically a camera, however, instead of using visible light for exposure it uses x-rays which are more energetic than typical light particles, this allows different material to be penetrated, the xray exposes the film the way that light would however since different matter within the body absorbs the xrays differently when they are exposed internal images are revealed.
How many X-ray apparatus companies are there?
The 1997 Economic Census reported 154 establishments for the irradiation apparatus industry, an increase of 17 percent from 1992.
Why is a x-ray machine a form of electromagnetic energy?
It is a form of electromagnetic energy because it uses special light rays to see through your skin/body to see your bones. It's heat and light is what makes it an excellent example of electromagnetic energy.
