X-Ray

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.

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.

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.

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.

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.

radon and polonium

yes there is something positive they are used in x rays and radiation. but they are very powerful they can penetrate concrete!

gamma rays can be used to kill insects and bacteria on foods. they are also used to steralize medical equipment. gamma rays also have a tissue penetrating property, making them useful in CT scans!

The first x-ray was taken in 1895 by Wilhelm Conrad Rontgen. He used an enclosed discharge tube of a cathode ray in a sealed, black carton so that no light would reach the tube, and but a paper plate covered in barium platinocyanide on ones side. The first x-ray was taken of his wife's hand.

Dr. Lassiter found a bullet lodged in Homer Sr.'s spine on the X-ray. It was located in the cervical vertebrae, between the 4th and 5th vertebra.

• Bullet lodged in spine
• Located in cervical vertebrae
• Between 4th and 5th vertebra

The AP dimension on an x-ray refers to the Anteroposterior dimension, which measures the distance from the front to the back of the body or structure being imaged. It provides information about the size and position of internal organs or bones.

By definition a lethal dose of x-rays would cause death.

Prior to death, the person would show signs of radiation poisoning including nausea, vomiting, hair loss, bloody vomiting (hemoptysis), bloody diarrhea (hematochezia), dizziness, low blood pressure (hypotension), slow wound healing, uncoordinated movement (ataxia), and seizures.

In practical purposes, a lethal dose of x-rays is nearly impossible since modern x-rays have such low levels of radiation.

For instance a single x-ray view of the chest is only 0.05mSv, which is the same amount of radiation you absorb from the ambient environment in 5 days. So, your risk of developing cancer, is only increased as much as it were to be if you were 5 days older than your real age.

For reference a lethal dose of radiation is approximately 30 Sv. So to get a lethal dose of radiation through x-rays you would need to get more than 600 x-rays in one sitting.

For x-ray examination of the lower gastrointestinal tract, the medical team typically consists of a radiologist, a radiologic technologist who operates the x-ray machine, and a nurse or medical assistant who assists the patient during the procedure. The radiologist interprets the images obtained during the examination to make a diagnosis, while the technologist ensures proper positioning and image quality.

Materials with high atomic numbers, such as lead, and dense substances like bone or metal, can block the passage of x-rays due to their ability to absorb and scatter the radiation. The level of attenuation depends on factors like the thickness and density of the material through which the x-rays are passing.

PMS on jewelry typically stands for Precious Metal Stamp, indicating the type of metal used in the piece, such as gold or silver. It helps verify the authenticity and quality of the metal used in the jewelry.

Periarticular sclerosis is increased bone density near a joint seen on X-ray, often due to chronic joint stress or osteoarthritis. Spurring along the superior acetabulum refers to bony growths at the top of the hip socket, typically seen in conditions like osteoarthritis or hip impingement. These findings can indicate degenerative changes in the hip joint.

Computed tomography scan

It's called CT scan.

The medical term for an X-ray record of the bile vessels is cholangiogram. This diagnostic imaging technique is used to visualize the bile ducts and detect any blockages or abnormalities.

Lucency on medical imaging, such as X-rays, is caused by the passage of X-rays through less dense tissues like air or fluid. This results in those areas appearing darker on the image. Lucency can be seen in conditions like pneumothorax (air in the chest cavity) or pulmonary nodules (small round growth in the lung).

A series of x-ray pictures that show the body in cross section are called CT scans (computed tomography scans). These scans provide detailed images of internal organs and tissues, helping to diagnose medical conditions.

Ask your Doctor, not the Internet! Your Doctor is there to help you. If you Doctor has not explained this, then you need to ask him or her.

X-rays are used for seeing an image of something inside of a item or a person.

DOCTOR :D

Depends on what type of setting you are in. I made $15.00/hour as a Limited Scope tech in a clinic. When I got my RT license, I went to work at a hospital, which has a starting pay as an RT of $19.00/hour. For Limited Scope at the hospital they only pay $13.75/hour.
