X-Ray

Exposure to radiation in the ultraviolet region is the most common way of causing fluorescence, but not the only way. Exposure to enough radiation for one electron to absorb two photons can cause fluorescence.

Sunscreen is used to protect the skin from ultraviolet radiation emitted primarily by our sun. The ozone layer also protects us from ultraviolet rays, however the current problems with holes in the ozone layer makes wearing sunscreen almost essential if one is going to be outside for an extended period of time.

Rosalind Franklin's work with X-ray diffraction involved exposure to high levels of radiation, which can damage DNA and increase the risk of cancer. This prolonged exposure to X-rays likely contributed to her development of cancer at an early age.

In order to solve the structure of a protein by x-ray crystallography, a biochemist must first find the conditions in which the protein is able to be crystallized. Some proteins have natively unstructured regions ("floppy parts") that make the protein unable to be crystallized. Many times, the protein will be recombinantly expressed without these unstructured regions, and the positions of these residues will not be found. Other times, the positions will not be found because there are too many alternate positions in the crystal and the locations of the residues will not be found in the electron density.

No, magnetic fields do not affect X-rays. X-rays are a form of electromagnetic radiation, while magnetic fields affect charged particles. Therefore, magnetic fields do not interact with X-rays in the same way they do with charged particles.

If we consider the bursts of high energy electromagnetic radiation from stellar or galactic sources, we encounter bursts of X-rays and gamma rays. The two are similar in that both are examples of high energy electromagnetic energy, and both can be generated by certain stars or galaxies. Additionally, both are the result of nuclear reactions in the star or at sites within the galaxy. But with gamma rays, the sources may be fewer than with X-rays, and the gamma rays are higher in energy than the X-rays.

Yes, there is some maximum of X-rays that a person can have. An X-ray (any X-ray) exposes the person being imaged to some amount of ionizing radiation. Ionizing radiation does some amount of biological damage. But an X-ray, in and of itself, won't "overexpose" an individual to a severe amount of radiation. A half dozen X-rays spaced out over a year given to someone who has needed, say, emergency medical services for injuries, will not usually present a problem.

If you have had an X-ray for any reason, let your medical providor or doctor know when you visit. Certainly you'll need to advise anyone who wishes to give you an X-ray that you've had one or two in the last few months. But it is difficult to get "too much" radiaton from X-rays unless someone is being medically treated with radiation for some reason.

There is no set limit to the number of X-rays someone may get. Is it ten? Or twenty? Who gets twenty X-rays in a year or two? There is a "weight" associated to each X-ray a person gets that might have to be factored in when determining whether someone has had "too much" of this kind of radiation. Unless someone is a radiation worker and/or has had or is undergoing radiation treatment, there is little reason to worry about any dangers from X-ray exposure.

MRI uses short bursts of radio, at frequencies of a few tens to a few hundreds of Megahertz.

Exactly the same radiation that comes out of an ordinary TV transmitter, but in short bleeps,

and without any sound or picture modulation on it.

Ozone, on the surface of earth is a corrosive and poisonous gas but at the height of 20-50 km from the Earth i.e. in the earth's atmosphere, becomes vital to life as it absorbs almost all u.v. radiations which are harmful to living things.

X-ray diffraction data of DNA revealed its double helical structure, with specific measurements indicating a helical repeat distance of around 3.4 angstroms and a complete turn every 10 base pairs. This data was crucial in understanding the molecular structure of DNA and its role in genetic information storage and replication.

An x-ray is a short wavelength, high frequency, high energy electromagnetic radiation lying between ultra-violet and gamma rays on the EM spectrum. Because they are so energetic, they can easily penetrate light materials (such as biological tissue), but are blocked by denser materials (such as metals or bone)

X-rays, which were discovered in 1895 by German physicist Wilhelm Röntgen. They are produced when high-speed electrons, accelerated by a high voltage, collide with nuclei in a metal target. The x-ray spectrum consists of a continuous bremsstrahlung emission, and characteristic, narrow emission lines which are specific to the material in the target.

When incident upon a surface, x-rays diffract, enabling us to determine properties of the material, such as its composition and structure.

X-rays pass through soft tissue and are blocked by hard tissue, which means that the lump is harder than the rest of your lung. Cancer tissue is not necessarily harder than other tissue, so don't jump to that conclusion. What can be harder in the lung tissue is tubercles, which are small growths caused by tuberculosis. Of course, you should follow whatever your doctor says about this, not something off WikiAnswers.

X-rays are a part of the electromagnetic spectrum. It consists of electromagnetic waves that have unique characteristics based on their wavelength or frequency.

Human beings can only perceive light that has a wavelength about 10-6 metres. This spectrum consists of all visible lights, from red to violet. X-rays, on the other hand have a wavelength of 10-10 metres, much beyond the range of the electromagnetic spectrum that is visible to the naked eye.

It is therefore not possible to see X-rays, although all of the electromagnetic spectrum is fundamentally the same. It is the inherent property of the human eye to be able to see only the frequencies that are present in the visible spectrum

Yes, placing an X-ray or gamma ray telescope on a mountain top can reduce atmospheric interference and provide clearer observations due to the thinner atmosphere at higher altitudes. This can improve the sensitivity and accuracy of the telescope in detecting these high-energy emissions from space.

Gamma rays and X-rays are harmful to students because they are forms of ionizing radiation that can penetrate the body, damaging cells and DNA. This can increase the risk of cancer and other health problems, depending on the level of exposure. It is important for students to limit their exposure to these types of radiation to protect their health.

X-ray's nickname is ironic because X-rays are a form of electromagnetic radiation that can penetrate solid objects, yet X-ray in the story has poor eyesight and needs glasses to see. This contrast between the powerful nature of X-rays and the character's visual impairment creates an ironic twist.

X-radiation (composed of X-rays) is a form of electromagnetic radiation. X-rays have a wavelength in the range of 0.01 to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3×1016 Hz to 3×1019 Hz) and energies in the range 120 eV to 120 keV. They are shorter in wavelength than UV rays and longer than gamma rays. In many languages, X-radiation is called Röntgen radiation, after Wilhelm Conrad Röntgen, who is usually credited as its discoverer, and who had named it X-radiation to signify an unknown type of radiation.

Rosalind Franklin, a biophysicist, used X-ray diffraction to capture images of DNA's structure. These images provided crucial data that helped Watson and Crick in determining the double helix structure of DNA.

A lamp or an X-ray tube cannot be used to "add neutrons" to other nuclei because lamps and X-ray tubes are not neutron sources.

Neutron activation is generally something we do in an operating nuclear reactor. In the core of the reactor, there is a high neutron flux. Many, many neutrons are being released in the fissions that are going on in the nuclear core. Materials that are to be activated are lowered through ports and brought down into the neutron flux. Activation occurs. Lamps or X-rays do not produce neutrons, and cannot be used in neutron activation activities. No neutrons means no neutron activation.

X-ray, being a photon, has no physical form or need for a shovel. This appears to be a play on words or a joke related to X-ray radiation passing through holes that are smaller than its wavelength, resulting in diffraction patterns.

X-rays are a form of electromagnetic radiation that can penetrate soft tissues like skin but are absorbed by denser materials like bones. The higher energy of X-rays allows them to pass through skin and create images of internal structures in medical imaging. However, prolonged exposure to X-rays can be harmful due to their ionizing nature.

Radium was used in the past for the treatment of some cancers and Marie Curie was a pioneer in this field. But radium don't emit x-rays; radium is a emitter of gamma, alpha and beta rays. The gamma radiation can destroy malign tumors.

In the book "Holes" by Louis Sachar, X-Ray is a teenage boy at Camp Green Lake who is the leader of the group of boys in Group D. He is known for his intelligence and ability to navigate situations strategically, often coming up with plans to find treasures in the desert. However, X-Ray can also be manipulative and self-serving at times, using his leadership position to his advantage.

Ultraviolet photons have wavelengths below 400nm. X-ray photons have wavelengths between 0.01nm - 10nm. Photons with wavelengths smaller than xrays' are called gamma rays.
