It's likely that you've had an x-ray in your lifetime – either at the dentist's or doctor's office. You also know that when you've had an x-ray you've had to remove earrings or other metal objects because the x-ray can't penetrate metal objects. While people do worry – and sometimes rightly so – about the radiation they are receiving by being subjected to x-rays the technology allows doctors the ability to see what's going on inside your body in a non-invasive way.
The way the x-ray technology works is by creating a concentrated beam of electrons and pushing them through a metal film. The result of the collision of the metallic film and super-charged electrons results in a high-energy electromagnetic radioactive surge. This radiation is what is termed an x-ray. The x-ray camera is equipped with a second metallic film that filters the image and prevents it from scattering it and making it impossible to decipher.
Calcium-enriched bones appear on the camera as outlines that the doctors utilize for diagnosis. Mineral deposits are also highlighted and these can help pinpoint the presence of tumors or other irregularities in the body. Sometimes, x-ray technologists have a patient ingest a contrasting agent such as iodine or barium to help make blood vessels and internal organs more easily visible on the x-ray.
It is true that high or frequent exposure to radiation over short periods of time can result in health issues but occasional exposure is considered a low risk proposition and isn't thought to result in permanent tissue or organ damage. Travelers also know that x-ray technology is utilized at the airport for baggage scanning and also by demolition crews to locate pipes and electrical lines. It's quite likely that the optical lenses found in medical, high tech and electronic applications were designed by UKA Optics.
