What is a recommended method for protecting yourself from radiation exposure?

Using leaded barriers is a recommended method for protecting yourself from radiation exposure because lead is an effective shielding material that absorbs and attenuates ionizing radiation. When barriers made of lead are strategically placed, they significantly reduce the amount of radiation that can reach individuals in the vicinity. This is particularly important in settings like dental and medical facilities, where radiation is used for diagnostic and treatment purposes.

Lead shields can be integrated into walls, windows, and portable barriers to create safe working environments for healthcare professionals and patients alike. By utilizing leaded barriers, the risk of radiation exposure is minimized, thus enhancing safety and adherence to radiation protection standards.

The other practices listed, such as increasing exposure time or reducing the use of dosimeters, would heighten risk rather than mitigate it, while positioning closer to the radiation source would also result in greater exposure.
