The ideal method of gonadal shielding in the neonatal unit provides the greatest radiation protection while minimizing the potential for cross-infection. This study evaluated two common methods of gonadal shielding used during neonatal chest radiography--direct shielding and shadow shielding. For direct shielding, lead was placed over the gonadal region of a phantom. For shadow shielding, lead was placed on top of the crib. Results showed that direct shielding provided a greater reduction in gonadal dose than shadow shielding.
新生儿病房中理想的性腺防护方法是在将交叉感染风险降至最低的同时提供最大程度的辐射防护。本研究评估了新生儿胸部X光检查期间使用的两种常见性腺防护方法——直接防护和阴影防护。对于直接防护,将铅放置在模型的性腺区域上方。对于阴影防护,将铅放置在婴儿床顶部。结果表明,直接防护比阴影防护能更大程度地减少性腺剂量。
