Although, many people had observed the effects of X-ray beams before, but Roentgen was the first one to study them systematically.
Moreover, who invented the X ray?
Wilhelm Conrad Roentgen
When was the x ray machine invented?
Before x ray machines were invented, broken bones, tumors and the location of bullets were all diagnosed by physical examination and a doctor's best guess. Patients paid the price of these approaches. Then on November 8th of 1895, a German physics professor Wilhelm Conrad Roentgen made a remarkable discovery.

What did Wilhelm Roentgen discovery?
Wilhelm Roentgen, Professor of Physics in Worzburg, Bavaria, was the first person to discover the possibility of using electromagnetic radiation to create what we now know as the x-ray. The image below is the first x-ray Roentgen ever created.

How does an xray work?
This beam travels through the air, comes into contact with our body tissues, and produces an image on a metal film. Soft tissue, such as skin and organs, cannot absorb the high-energy rays, and the beam passes through them. Dense materials inside our bodies, like bones, absorb the radiation.

Are xrays Harmful?
Generally, the amount of radiation you're exposed to during an X-ray is the equivalent to between a few days and a few years of exposure to natural radiation from the environment. Being exposed to X-rays does carry a risk of causing cancer many years or decades later, but this risk is thought to be very small.

How gamma rays are used?
X-rays, gamma rays and beta particles are all used in medicine to treat internal organs. X-rays are produced by firing electrons at a metal target and gamma rays are emitted by the nucleus of radioactive atoms. Gamma rays are used to kill cancer cells, to sterilise medical equipment and in radioactive tracers.
5
What do gamma rays cause?
X-rays and gamma rays are known human carcinogens (cancer-causing agents). It is harder to measure the much smaller increase in cancer risk that might come from much lower levels of radiation exposure. Most studies have not been able to detect an increased risk of cancer among people exposed to low levels of radiation.
6
Can gamma rays hurt you?
Gamma rays can interact with cells in the body and make them non functional or they can mess up a cell's DNA and cause mutations when it divides. There are many, many cells in the body so you can lose some of them without any harm. If you lose too many you can get sick or with massive doses, can die.
7
Can gamma rays turn you into the Hulk?
Gamma rays are blamed for making Bruce Banner the Incredible Hulk. Unlike the Incredible Hulk, gamma rays are not green — lying as they do beyond the visible spectrum, gamma rays have no color at all that we can describe. Death rays. Exactly how Bruce Banner survives his transformation is unclear.
8
How can gamma rays be harmful to the body?
If the radioactive source is outside the body: Alpha radiation is not as dangerous because it is unlikely to reach living cells inside the body. Beta and gamma radiation are the most dangerous sources because they can penetrate the skin and damage the cells inside.
9
Can gamma rays pass through the human body?
Internal exposure to beta particles causes much more severe symptoms than external exposure. Gamma rays are the most dangerous form of ionizing radiation. If you're exposed to gamma rays, they pass through your entire body, affecting all of your tissues from your skin to the marrow of your bones.
10
Why is radiation harmful to humans?
Ionizing radiation happens when the atomic nucleus of an unstable atom decays and starts releasing ionizing particles. When these particles come into contact with organic material, such as human tissue, they will damage them if levels are high enough, in a short period of time.
11
Can you get cancer from radiation?
Prolonged exposure to ultraviolet radiation from the sun can lead to melanoma and other skin malignancies. Clear evidence establishes ultraviolet radiation, especially the non-ionizing medium wave UVB, as the cause of most non-melanoma skin cancers, which are the most common forms of cancer in the world.
12
Is there any good radiation?
In other words, not only is there a threshold for radiation exposure – a limit below which radiation should not be harmful– but at certain low levels ionizing radiation may do more good for your cells than harm. The idea that a low dose of a bad thing can have good effects is called hormesis.
13
How much radiation is safe for humans?
Average Natural Background: 300 Millirems. The average exposure in the United States, from natural sources of radiation (mostly cosmic radiation and radon), is 300 millirems per year at sea level. Radiation exposure is slightly higher at higher elevations-thus the exposure in Denver averages 400 millirems per year.
14
Where does the most radiation come from?
This exposure primarily comes from cosmic rays, radioactive material in the earth (such as uranium-238), ingestion of naturally occurring radionuclides in food (such as potassium- 40), and inhalation of radon gas. In the United States, the average background radiation dose is 300 mrem/yr.
15
Is there man made radiation?
Radioactivity, a Natural or Man-Made Phenomenon. The decay of unstable atoms releases radiation, a phenomenon called radioactivity. As unstable atoms exist in all matter, we are surrounded by natural radiation. Radiation can also come from man-made sources, through military, medical or industrial applications.
16
What is the most common source of radiation exposure?
Most of this kind of radiation people are exposed to comes from the earth in the form of radioactive elements which can decay, such as radon gas (which seeps out of the earth and may collect in people's basements), and cosmic rays.
17
What are the three sources of radiation?
The Earth itself is a source of terrestrial radiation. Radioactive materials (including uranium, thorium, and radium) exist naturally in soil and rock. Essentially all air contains radon , which is responsible for most of the dose that Americans receive each year from natural background sources.
18
What are the man made sources of radiation?
By far, the most significant source of man-made radiation exposure to the public is from medical procedures, such as diagnostic X-rays, nuclear medicine, and radiation therapy.
