X-rays and gamma rays — rays that changed the world of science

as if Robert Hazen, Ph.D., George Mason University

X-rays and gamma rays are high-energy radiation that can be used and produced by technology. Ionizing X-rays are about 0.1-100 billion inches, and gamma rays are less than 100 trillion meters long. The longer the wavelength, the lower the power, and vice versa.

How X-rays are produced?

X-ray was discovered by Wilhelm Conrad Roytegen, who lived in 1895 from 1845 to 1923. X-rays, like all electromagnetic radiation, are produced by accelerating electric charges. The X-ray tube emits X-rays in a very simple way, and the way it works is very similar to a light bulb, one important difference.

In an X-ray tube, a very high negative voltage is applied to the thread and a high positive voltage is applied to the copper or molybdenum or other metal plates. When that high voltage step is applied, sometimes 50,000 volts, the electrons boil the hot wire, and they fall down and break into the plate.

At such high speeds, those charged particles are emitted rapidly and must emit electromagnetic radiation. After all, accelerating or minimizing electromagnetic radiation is just a matter of vibrating charged particles.

These electrons break into the plate and vibrate, and that creates an X-ray. X-rays are then emitted from the port by direct radiation, which can be used in a variety of scientific or technological experiments.

X-ray in medical science

The great penetration of these rays, coupled with the fact that they are held in place by some photographic plates, makes them ideal for viewing hidden structures in the body.

They do medical X-rays because the tissue parts are clear or large for them, but the bones contain a lot of X-rays, so the doctor can compare the film and begin to look at the internal structures of the body.

And this is how a dental x-ray works. X-rays pass through the cheeks, gums, teeth, and film. The dentist can then see if there are any gaps, because, of course, the gaps are not X-rays, but teeth.

Gamma rays

And then we come to the gamma rays, the maximum electromagnetic waves. Remember, all electromagnetic radiation is vibrating, electric charges are vibrating. And this is true for gamma rays, but this does not happen with electrons, but with protons in the atomic nucleus.

The nucleus is a very high energy field, and gamma rays emanate when protons in the nucleus accelerate.

There are state-of-the-art laboratories in Tennessee that produce small-scale gamma rays, such as radioactive chemicals, and a variety of research materials.

Gamma rays – uses and applications

Gamma rays are used for medical examinations, and the doctor can then transfer a small amount of the gamma ray to a specific part of the body, and see if the chemical enters the tissues or how that organ works. To a specific entity.

For example, a doctor may inject a gamma-ray-containing phosphorus injection into a patient’s bloodstream, and that phosphorus compound can be collected in the area where the bones are healed, where the fracture itself is repaired, and doctors can monitor it. The process of healing the bones just by looking at the chemical produced by gamma rays.

Physicists use gamma rays to study the structure of atoms, and astronomers are interested in the distant sky because of the production of gamma rays.

ELF: Extremely low frequency waves

Obviously, shorter wavelengths are more dangerous, more powerful. But in recent times, there has been controversy over long wavelengths, the low end power, and long wavelengths beyond radio waves. These are called ELF, or very low frequency waves.

Waves 60 cycles per second, used to generate energy in a power plant. They do not have real technology applications, but they are permanently produced locally by the various devices used by humans. There is another ELF range of 15,000 to 30,000 cycles per second. Those are set up in video display terminals.

Recently, there have been several government reports on low-frequency radiation requests. Most people are not at risk. However, there are significant risks associated with certain types of work. Power line workers, or those sitting in front of a video display for several, several hours, may be exposed to some of the average levels of this radiation.

Are X-rays and gamma rays dangerous?

To date, there is no convincing evidence. A survey of 36,000 electricians was conducted in California. There was no risk of cancer among those workers. Then 138,000 consumers were surveyed in North Carolina. There is no risk of developing leukemia, but there is probably a slightly higher risk of brain cancer.

So, if there is a link there, it is not really clear. And then there was the study of 223,000 consumer workers in Canada and France. And that has slightly increased the risk of leukemia, but it does not increase the risk of other types of cancer, and so people keep statistics here. Much more research is needed.

Common questions about X-rays and gamma rays

Q: What is the difference between X-rays and gamma rays??

X-rays and gamma rays Vibration in the electromagnetic field is both electromagnetic radiation. The difference between the two is their wavelength. Gamma rays are shorter than X-rays.

Q: How are X-rays and gamma rays used?

X-rays and gamma rays They are widely used in the medical industry. They are used to diagnose internal diseases and to monitor the condition of the body.

Q: Are X-rays and gamma rays dangerous?

Many studies have been conducted on hazards X-rays and gamma rays, And so far there is no evidence that they are dangerous.
