Which of the following measures helps minimize radiation exposure?

Minimizing radiation exposure is crucial in physical therapy and other medical settings where radiation is utilized. Each of the measures listed plays an essential role in protecting both patients and healthcare workers from unnecessary radiation exposure.

Increasing the distance from the source is a fundamental principle in radiation safety. The intensity of radiation decreases with distance due to the inverse square law. This means that the further one is from the source of radiation, the lower the exposure will be. By maintaining or increasing the distance from the radiation source, the risk of exposure significantly diminishes.

Decreasing the time of exposure is another critical strategy. The less time spent near a source of radiation, the lower the dose received. In many medical and therapy scenarios, it’s possible to limit the duration of exposure without compromising patient care or outcomes. This principle underscores the importance of efficiency and minimizing unnecessary procedures that involve radiation.

Using shielding barriers is an effective way to protect individuals from radiation. Barriers made from lead or other materials can absorb radiation and prevent it from reaching healthcare providers and patients. This is particularly important during procedures that involve high levels of radiation.

Since all of these measures are valid and effective strategies for minimizing radiation exposure, the comprehensive approach of employing each method reinforces the importance of safety protocols in any setting
