X-Ray

X-ray is a safe and painless process which frequently used to create inside images of the body. An effective way of observing the fractured bones, such as a broken arm, wrist or feet etc. X-ray may also be used to scan organs and detect complications. X-ray can detect a lung infection, like pneumonia. X-ray is used by surgeons during healing process such as a coronary angioplasty, to guide equipment to the area being treated.

X-rays are type of radiation. X-rays have high frequency and short wave length as compared to light, thus they pass through the human body, the energy particles called Photon are absorbed at different rates. White areas are the dense matter the darker areas are the softer parts such as lungs and heart, on the X-ray image

Radiography is imaging technique that uses electromagnetic radiation i.e X-rays, to view the internal structure in the human body. X-rays are carried out by radiographers, professionals who are trained to use imaging technology. The part of the body which is to be examined is place between the X-ray machine and the photographic plate. As the X-rays hit the photographic plate a snap shot of the image is formed on the plate. Exposure to high levels of radiation can be very harmful.

X-rays uses

Medical Use
Fractured bones, detect kidney stones, cancer, ulcers, and other medical issues.To detect diseases of the teeth.  Used to cure malignant and benign tumors, X-rays are also used to treat bursitis and leukemia.
     
Used for industrial purpose: to remove beryl from granite ,to check aeroplane and vehicles parts, plastics,rubber goods, metal castings etc.

Other uses: to study the structure of crystals or molecules. Forensic study locate bullets and other foreign objects within the body. To check customers and baggage at Airport , Railway Stations, etc.To check  paintings whether genuine or copies. To read parchments that would fall apart if unrolled like National Archive documents, the Dead Sea Scrolls etc. 

German physicist called Wilhelm Conrad Rontgen discovered X-rays  in 1895  almost by accident. Experiments in which he passed an electric current through Crookes tubes, Rontgen noticed that photographic plates grew fogged. He placed black paper on the tube and then switched on the current.Nearby a screen coated with barium began to glow. This caused him to believe that unknown rays produced inside the tube were passing through the paper to make this fluorescent substance give out light. Since x is a scientific numeral for anything that is unknown, he named them X-rays. Rontgen took an X-ray photograph of his wife's hand Anna which clearly revealed her wedding ring and her bones.

In 1901 Rontgen was awarded the very first Nobel Prize in Physics.
