Did you know that the dental xray was first discovered, then used, in 1895? Since then, xrays have not only become safer, but they have also become more exact, and are used on all parts of the body in order to determine issues, not just the teeth. Radiology is the study of images made of the human body, and a radiologist is a doctor who has been trained to interpret medical images, and understands how to operate and perform imaging procedures.
It is important that doctors regularly check imaging and radiographic machines in order to monitor the amount of radiation coming from them. Even though xrays emit a relatively small amount of radiation, it is important to shield both patients and doctors just in case. For doctors and people working with xrays constantly, this is necessary since they will be experiencing repeated and daily exposure to the radiation.
There are many tools and xray accessories used to prevent xray radiation from entering the body. Lead aprons and lead glasses are often used to contain xrays and prevent them from reaching potentially vulnerable parts of the body. Prolonged radiation exposure has been shown to cause cancer. The lead used in lead aprons and leaded glasses absorbs x rays, beta particles and alpha particles. Lead aprons protect the vital organs of both patients and technicians. Radiation protection products are required for use by anyone handling xray equipment.
