X-Ray

Marie Curie did not invent the x-ray. Roengten did.

Roengten discovered X-ray on November 8, 1895. He took an X-ray of his wife's hand a week later.

Coolidge developed the x-ray tube.

Marie Curie improved the x-ray tube and developed an X-ray unit that was used in WWI, a mobile unit.

Gamma rays are more energetic because they have a higher frequency. The operate on the order of 10^19 Hz, whereas X-ray frequencies are typically an order of magnitude or two smaller.

Energy is related to frequency by Max Planck's equation E=hf, where h is Planck's constant (6.626x10^-34 Js) - we see this product yields the unit Joules.

Frequency and wavelength are easily related knowing light travels at a finite speed of about 300,000,000 m/s-

300,000,000 m/s = wavelength (m) * frequency (1/s)

If a gamma ray has 10^19 Hz frequency,

( 300,000,000 m/s ) / ( 10^19 s^-1 ) = wavelength (m) =~ 3x10^-11 m = 0.03 nm

If an x-ray has 10^17 Hz frequency,

( 300,000,000 m/s ) / ( 10^17 s^-1 ) = wavelength (m) =~ 3x10^-9 m = 3 nm

The higher frequency photon can be thought of as more energetic since more successive wavelengths pass through a given point per second.

what is the required safe distance to stand from a portable x-ray

An X-ray is a machine that uses radiation to see "through" to your bones, but since it has to produce an HD picture of something INSIDE you, it's gonna take a while. If you stand still, it can produce the image easily. If you move, it will come out blurry. It's almost like taking a picture or painting someone, or maybe even sculpting someone.

[fôreks′, fīveks′]

the designations for abnormal sex chromosome complements in the human female in which there are, respectively, three, four, or five instead of the normal two X chromosomes so that each somatic cell contains a total of 47, 48, or 49 chromosomes. Although there is no consistent phenotype associated with such aberrations, the risk of congenital anomalies and mental retardation in the affected individual increases significantly as the number of X chromosomes increases.

No. Only the spaces where the disks are. And MRI or CT scan can actually image the disk itself.

radiopaque

X rays are are able to penetrate less dense materials easily, such as muscle and skin tissue in medical situations or plastics and wood in other applications.

As the material becomes more dense, the x rays penetrate less easily.

Materials such as steel or bone in a medical setting are more dense along with such materials as lead and tungsten in engineering situations.

There is some confusion here.

Wavelengths are measured in units of length, such as meters, kilometers, nanometers, etc.

Frequency is measured in hertz.

X-rays are electromagnetic waves, so they can travel in empty space. (Space itself is the "medium" in this case.)

If X-Rays did not exist, then people would not know how severe their broken bone is, or they would not know if they have broken a bone in an injury. X-Rays are very important because they help you with your health and your bones.

In Germany

for a PA chest x ray you center at the tip of the scapula located at T7,

then you simply rotate the patient so that their left side is against the image receptor for the lateral and both arms out in front of them and up (the film may move down a maximum of 2 inches for the lateral if apices appear low on PA image)

people can check bones if it,s broken or not

areas which are less dense and have allowed more xrays to pass through. eg Black = air, softer tissues. White= bone/ calcification
