What is an effective method to minimize exposure to radiation?

Using lead aprons is an effective method to minimize exposure to radiation due to their ability to absorb and attenuate radiation. Lead is a dense material that effectively blocks or reduces the intensity of ionizing radiation, which makes lead aprons commonly used in medical settings, such as during X-ray procedures and certain types of diagnostic imaging. By wearing a lead apron, individuals receiving or administering radiation can significantly decrease their radiation dose, thereby improving safety and reducing potential health risks associated with radiation exposure.

The other methods provided are not effective in minimizing radiation exposure. For instance, increasing proximity to the source would actually increase exposure since radiation intensity decreases with distance according to the inverse square law. Wearing thin clothing does not provide adequate protection from radiation. Additionally, extending the duration of exposure would lead to a higher accumulated dose of radiation over time, which is contrary to the goal of minimizing exposure.
