Portable X-rays remain one of the most frequently used diagnostic procedures in neonatal intensive care units (NICU). Premature infants are more sensitive to radiation-induced harmful effects. Dangers from diagnostic radiation can occur with stochastic effects. We aimed to determine the radiation exposure in premature infants and staff and determine the scattering during X-ray examinations in the NICU.
In this prospective study, dosimeters were placed on premature infants who were ≤1,250 g at birth and ≤30 weeks of gestational age who stayed in the NICU for at least 4 weeks. The doses were measured at each X-ray examination during their stay. The measurements of the nurses and the doctors in the NICU were also performed with dosimeters over the 1-month period. Other dosimeters were placed in certain areas outside the incubator and the results were obtained after 1 month.
The mean radiation exposure of the 10 premature infants, monitored with dosimeters, was 3.65 ± 2.44 mGy. The mean skin dose of the six staff was 0.087 ± 0.0998 mSV. The mean scattered dose was 67.9 ± 26.5 µGy.
Relatively high exposures were observed in 90% of the patients and two staff. The radiation exposure levels of premature infants and staff may need to be monitored continuously.
· The premature infants are exposed to radiation due to the bedside X-rays.. · The radiation exposure levels of premature infants and staff may need to be monitored continuously.. · Measures and alternative methods to reduce radiation exposure should be encouraged..
便携式 X 光机仍然是新生儿重症监护病房（NICU）中最常用的诊断程序之一。早产儿对辐射诱导的有害影响更为敏感。诊断辐射的危险可能来自随机效应。我们旨在确定早产儿和工作人员的辐射暴露情况，并确定 NICU 中 X 射线检查时的散射情况。
在这项前瞻性研究中，将出生体重≤1250g 且胎龄≤30 周、在 NICU 中至少停留 4 周的早产儿放置在剂量计上。在他们的住院期间，每次 X 射线检查时都会进行剂量测量。在 1 个月的时间内，还使用剂量计对 NICU 中的护士和医生进行了测量。还在孵化器外的某些区域放置了其他剂量计，并在 1 个月后获得了结果。
使用剂量计监测的 10 名早产儿的平均辐射暴露量为 3.65±2.44mGy。6 名工作人员的平均皮肤剂量为 0.087±0.0998mSV。平均散射剂量为 67.9±26.5µGy。
90%的患者和 2 名工作人员的辐射暴露量相对较高。可能需要对早产儿和工作人员的辐射暴露水平进行持续监测。
·由于床边 X 射线，早产儿会受到辐射。·可能需要对早产儿和工作人员的辐射暴露水平进行持续监测。·应鼓励采取措施和替代方法来减少辐射暴露。
