Which of the following represents the basic principles of radiation protection for patients?

The basic principles of radiation protection for patients are centered around the concepts of time, distance, and shielding.

Time refers to the duration of exposure to radiation; minimizing the time spent in the radiation field helps reduce the dose received by the patient. The longer the exposure, the greater the amount of radiation the patient may absorb, therefore limiting the time is crucial for safety.

Distance is the second principle and involves maximizing the distance between the source of radiation and the patient. According to the inverse square law, as the distance from the radiation source increases, the intensity of radiation decreases. Therefore, increasing the distance can significantly diminish the radiation dose received.

Shielding involves using materials that block or absorb radiation to protect the patient from unnecessary exposure. Common materials for shielding include lead or other dense substances that can absorb or scatter radiation effectively.

The other options do not accurately reflect these core principles of radiation protection. For instance, incorporating temperature and texture has no relevance to radiation safety, and concepts like dosage management or feedback mechanisms do not align with the essential protective measures established in radiation safety guidelines.
