What percentage of x-ray attenuation does a 0.5-mm lead-equivalent apron provide at 75 kVp?

A 0.5-mm lead-equivalent apron provides 88% attenuation of x-rays at 75 kVp, which reflects the apron’s effectiveness in reducing radiation exposure.

The concept of lead equivalency is crucial in radiation protection because it quantifies the shielding capability of a material compared to lead. At 75 kVp, the performance of the apron is measured in terms of its ability to absorb x-ray photons and prevent them from reaching the patient or healthcare worker.

The percentage indicates the proportion of the initial radiation intensity that is reduced by the apron, highlighting its protective quality. In the context of radiation safety, wearing an apron that provides 88% attenuation significantly lowers the risk of radiation exposure during diagnostic imaging processes, making it an essential component of protective measures in radiology and other medical fields involving x-ray usage.
