As you watch TV, microwaving a pizza, or sitting at your computer surfing the Internet, you are being injured by intangible rays of radiation. Rest assured that the amount of radiation which you absorbs is very small. Radiography is a medical term to describe programs which use radiation to help doctors diagnose patients. Common radiography techniques refer to X-rays and CT scans. When the radiation you absorb in these programs is higher than normal, safety is considered firstly.
Security measures in X-Rays
An X-ray is a medical program whereby the patient is injured with X-rays and afterward a picture of the patient's insides can be checked by a doctor to help him make a diagnosis. Generally, the program is very safe. One method radiography technicians make this program safe is decreasing the dosage of radiation. In a year, a person will absorb about 3 millisieverts of radiation. In general, the amount of radiation absorbed during an X-ray is the amount an average person would receive in 10 days.
In addition to using a very small amount of radiation, the patient is typically given a lead vest to wear. This vest protects the patient from redundant X-rays by, substantially, shielding or interdicting the redundant radiation waves from penetrating the body. By controlling the level of radiation and making it minimal and providing the patient with a lead vest, X-ray radiography is a safe medical program.
CT Safety
CT safety generally abides by the same lines of idea as X-ray safety. In a CT scan, X-rays are combined with computer technology to provide cross-sectional images. These images tend to announce more information than traditional X-rays. The Federal Drug Administration (FDA) has set forth a few guidelines for CT safety; the FDA admit that these programs are not new and many facilities carry out them. Moreover, the FDA suggests decreasing the current in the CT tube; doing that will decrease the radiation further. This program should only be used if necessary; that is, when the CT scan can announce more information than a traditional X-rays, it should not be used if a traditional X-ray is all that is needed.
