What are the advantages and disadvantages of X Ray telescopes?
Advantages of X-ray telescopes include the ability to capture high-energy emissions from objects such as black holes and neutron stars, providing valuable information about these phenomena. However, X-ray telescopes are limited by Earth's atmosphere, which absorbs X-rays, necessitating the need for them to be placed in space. Additionally, X-ray telescopes tend to have lower resolution compared to optical telescopes.
It is a medical concoction that is used to provide contrast in the X-rays, during an Upper G.I. exam. It is comprised of Barium Sulphate.
Why can ultraviolet light and X-rays and gamma rays be both helpful and harmful?
Ultraviolet (UV) rays can help kill bacteria, but being exposed to a source like the sun for an extended period is not healthy as that exposure can damage skin. X-rays are used in medical imaging, and they can greatly assist professionals wishing to make a medical diagnosis. The energy of these rays is high, however, and X-rays can cause tissue damage. Exposure must controlled to minimize risk. Gamma rays are even more energetic, and they can be used to treat things like cancer. But these rays, too,
can cause tissue damage, so radiation treatment must be carefully administered.
X-rays themselves do not hurt. However, some people may experience discomfort or pain if the X-ray technician needs to position them in specific ways for the imaging.
Electromagnetic energy is the most important form of energy in radiography, as it is present in both x-ray beams and magnetic resonance imaging. Electromagnetic energy is responsible for the creation and transmission of the imaging signals used to produce diagnostic images in radiology.
What is the expected lifespan of Chandra X-ray Observatory?
Prior to being launched into space on 23 Jul 1999 on STS-93, the Chandra X-Ray Observatory (CXO) was given an expected lifetime of 5 years. In September 2001 NASA extended the CXO's lifetime to 10 years "based on the observatory's outstanding results."
Physically the observatory could last for much longer. A study performed at the Chandra X-ray Center indicated that the CXO could last at least 15 years.
Because current technology cannot significantly improve upon the resolving power of Chandra's mirrors, it's unlikely that another x-ray observatory will be launched before 2015. So we'll probably get to see just how long Chandra can last.
Why can't barium carbonate replace barium sulfate in stomach x-rays since both are insoluble?
Barium carbonate will react with hydrochloric acid in the stomach forming soluble barium chloride which can be absorbed into the blood.
BaCO3(aq) + 2HCl(l) ---> BaCl2(aq) + CO2(g) + H2O(l)
Barium sulphate, however, does not react with hydrochloric acid in the stomach. Thus, it passes straight through the alimentary canal unchanged and the individual is not poisoned.
How are atoms in an X-ray tube anode ionized?
The atoms in the anode of an X-ray tube are ionized by an incoming beam of high energy electrons. Those electrons streamed off the cathode and were accelerated by the high voltage across the tube's elements. The high energy electron beam slams into the specially alloyed anode and ionizes the atoms there. The ionized atoms have their outer electrons torn out to very high energy levels, and when they de-ionize, they do so by emitting a high energy photon - an X-ray. The anode gets hot as heck, too.

X-ray film is chemically sensitive film. It is created to react with the sourced light producing an image. It was made possible through the advances of Marie Curie and her studies of extracting radium from pitchblende.
Who is the famous discoverer of X-ray?
Willhelm Rontgen is usually credited as the discoverer.
He called it X-Radiation to signify an unknown type of radiation.
What are the applications of x ray crystallography?
It is mainly used to predict arrangement of atoms within large biological macromolecules.
It determines X,Y,Z coordinates of all atoms.
It is used to find three dimensional structure of a molcule, so that it can be docked with a ligand molecule.
What shape was suggested by rosalind franklin's x-ray images?
Rosalind Franklin's x-ray images of DNA suggested a helical shape, specifically a double helix structure. This played a crucial role in the discovery of the structure of DNA by Watson and Crick.
What do UVB rays do to the skin?
UVB rays have the wave length ranges 315-280 nm. It is used in treatment for many skin disorders like vitiligo, eczema etc.
From the Related link (UVB Radiation...) below: "The UVB rays are mostly responsible for most cases of sunburn, as they are shorter than UVA rays and only reach the surface of the skin that is made up of the epidermis layer. The UVB radiation is absorbed by the stratum corneum on the epidermis surface. This stratum corneum is the dead cells layer - the visible layer of the skin. The UVA radiation is partly absorbed and blocked by the ozone layer before reaching Earth.
The UVA damage is deeper, as the UVA rays are longer than the UVB ones and reach the inner strata of the skin. They are responsible for causing the skin to lose its elasticity and wrinkling, leading to premature aging of the skin. They also can burn the skin, but at a deeper level. The UVA rays are not at all absorbed by the atmosphere and completely reach Earth.
Both UVA and UVB lead to skin cancer, whether it is malignant or benign. In the malignant type of cancer there is a tumor that appears as a consequence of abnormal proliferating skin cells. The uncontrollable growing of these cells leads to melanoma tumor forming, which in most of the cases is lethal."
What are gamma rays most similar to?
A gamma ray is a form of electromagnetic radiation that has a very short wavelength (and a very high frequency and a very high energy). Gamma rays are similar to visible light, radio waves, and all the other forms of electromagnetic radiation. We find gamma rays at the top or high end of the electromagnetic spectrum. It is probable that X-Rays, which are just below gamma rays in the spectrum, are most similar.
Who found a relationship between the wavelengths of x-rays and the atomic number of elements?
Henry Moseley found the relationship between the wavelengths of x-rays and the atomic number of elements. He proposed that the atomic number of an element is better defined by the number of protons in the nucleus rather than by its atomic mass.
How does aluminum block ultraviolet light rays?
Aluminum is a highly reflective material that can reflect most of the ultraviolet light rays that come in contact with it. This property helps to protect surfaces coated with aluminum from the damaging effects of UV radiation.
To differentiate between A-type, B-type, and C-type X-ray diffraction patterns of starches, you can analyze the characteristic peaks and patterns. A-type starches exhibit characteristic peaks around 15° and 23°, B-type starches have peaks at around 17° and 23°, while C-type starches show peaks at around 5° and 20°. By comparing the diffraction peaks of your sample with these known patterns, you can determine the type of starch present.
Colleges with x-ray technician programs?
listen.......was trying to start the thread on DISCUSSIONS,but no link. trying to find a college in nyc offering this is beyond belief. trying to find an accredited cetificate type of program is well beyond the limits of belief.... better to research certain hospitals still offering a 2 year course in radiology which today must yield an associates . bellevue,nyu etc have programs BUT to find them on the internet even with google is a frustrating task. maybe go through "cuny" and see what programs they are offering ? there are SOMEWHERE within the 5 boros of nyc,technical schools offering the course which will lead to a certificate /LICENSURE which will take you as far as you want to proceed but at least you can work a nd get paid. PS--i am NOT a spammer or a vandal,simply another person SEARCHING for an accredited program and came upon wiki via google--hoping for an answer as they have on google this posted question.
UV rays are danerous because they can burn your skin. But they also kill bacteria and UV is also used to detect forgery.
