Most commonly known for their use in medical and security applications, X-ray permit the inspection of internal and hidden structures, and have many modern applications in industry. A form of electromagnetic radiation, X-ray are used to develop images, just as light is used in normal photography. Also, depending on their wavelength, X-ray can be classified as soft or hard.
X-rays are most commonly used to find broken bones and to photograph the internal structures of teeth such as in the case that a child needs her cavities filled. In receiving an X-ray, a patient normally wears a lead-lined blanket or vest to protect surrounding tissue from unnecessary exposure (lead blocks radiation). Even though the amount of radiation absorbed from one application is small, it is never the less toxic.
Most scientists agree that it’s important to limit radiation exposure wherever possible to minimize TBB (total body burden), a measurement that sums all toxins impacting the body at any given time. Indeed, excessive exposure to X-rays can lead to all sorts of negative consequences, everything from hair-loss to cancer, to death. For that reason, government health agencies have set limits on the people who work regularly with X-rays, such as medical technicians, and generally, they are required to leave the room altogether when an X-ray machine is imaging.
