Final answer:
Shoring and shielding are health and safety techniques in radiography that use materials such as lead to protect against radiation exposure, with examples including lead aprons for patients and protective barriers for technicians. Fast films also contribute to safety by reducing exposure time.
Step-by-step explanation:
The correct answer is option Health. In the context of medical diagnostics and radiography, shoring and shielding are techniques used to protect patients and medical personnel from unnecessary exposure to radiation. Shielding involves using barriers of lead or other materials to absorb X-rays and gamma rays.
For example, lead aprons are commonly placed over patients during dental X-rays to protect other parts of the body, and the X-ray tube itself is surrounded by protective shielding. Moreover, the use of fast films reduces the time required to capture an image, further reducing radiation exposure. The distance from the radiation source is crucial as well; increasing the distance reduces the intensity of exposure, which can be illustrated by dental technicians standing behind protective barriers. Lastly, decreasing the exposure time to radiation is an effective way to minimize dose received by an individual.
