The full form of X-Ray is X-Radiation. X-Ray is basically a form of electromagnetic radiation. X-Rays have a shorter wavelength than Ultra-Violet Rays and have a longer wavelength than Gamma Rays. The name X-Radiation was named after Wilhem Conrad after he discovered an unknown type of radiation.
The uses of X Rays are useful in the detection of pathology of the skeletal system as well as for detecting some disease processes in soft tissues The different medical uses are the common x rays, computer tomography, fluoroscopy and radiotherapy.
However, the risk of X-rays are a form of ionizing radiation, hence causing radiation sickness. When normal light hits an atom, it can't change the atom in any significant way. But when an X-ray hits an atom, it can knock electrons off the atom to create an ion, an electrically-charged atom. Free electrons then collide with other atoms to create more ions. An ion's electrical charge can lead to unnatural chemical reactions inside cells. Among other things, the charge can break DNA chains. A cell with a broken strand of DNA will either die or the DNA will develop a mutation. If a lot of cells die, the body can develop various diseases. If the DNA mutates, a cell may become cancerous, and this cancer may spread. If the mutation is in a sperm or an egg cell, it may lead to birth defects. Because of all these risks, doctors use X-rays sparingly today.

How frequent can we take a X-ray a year? How does the radiologist protect themselves since they need to be exposed to X-ray frequently
ReplyDeleteWell explained (Y)...However you could elaborate more on the part about "X Rays are useful in the detection of pathology of the skeletal system"
ReplyDeleteThere are a lot of information and it is very specific
