Why Shielding Isn’t Always the Best Protection

For decades, lead aprons and gonadal shields were standard practice in X-ray imaging. However, leading radiation safety experts now advise against routine patient shielding during diagnostic X-ray procedures — and for good reason.

Organizations like the National Council on Radiation Protection and Measurements (NCRP) and the American Association of Physicists in Medicine (AAPM) have issued evidence-based recommendations that show shielding can sometimes do more harm than good.

What’s Changed

Thanks to modern imaging technology, radiation doses in diagnostic exams are significantly lower than they once were, and the risk to patients — especially reproductive organs — is now minimal.

According to NCRP Statement No. 13:
“Use of patient gonadal and fetal shielding during abdominal and pelvic radiography is not recommended as routine practice.”

Here’s why:

• Shielding can interfere with automatic exposure controls, which may actually increase the dose of radiation.
• Misplaced shields can obscure anatomy, potentially leading to repeat exams — and more exposure.
• Shields do not significantly reduce radiation to internal organs due to scatter and internal absorption.

Backed by Science

The AAPM supports discontinuing routine shielding of patients during X-ray imaging, stating:
“There is no scientific evidence that shielding benefits the patient under current best practices, and shielding may adversely affect the diagnostic quality of images or increase the radiation dose.”

Patient Safety Is Still the Priority

Eliminating routine shielding does not mean less protection. In fact, it reflects our commitment to using the most up-to-date scientific standards to keep patients safe. With today’s technology, we can minimize radiation exposure more effectively through optimized techniques and equipment — not outdated shielding methods.
