为了确保医疗机构医务人员的安全,像防护服这样的辐射屏蔽材料用于防止低剂量辐射,如散射的光线。四肢,尤其是手,最容易受到辐射。可以直接涂在皮肤上的新材料将更具成本效益,高效,而且比手套方便。我们使用环保屏蔽材料开发了防护面霜,包括硫酸钡,氧化铋,还有氧化镱,为了避免铅等重金属的有害影响,并测试了它们的皮肤保护效果。特别是,比较了氧化镱与其他材料的辐射屏蔽效果。由于屏蔽材料的分散和层厚度极大地影响了防辐射霜的功效,我们根据重量百分比(wt%)评估分散。有效辐射能量减少了20%,奶油厚度增加了1.0毫米。氧化钇比其他两种材料具有更高的辐射屏蔽率。在不同的重量%下观察到28%的保护效果差异,在63.4keV辐射下45重量%的乳膏实现了61.3%的降低率。更高的含量导致更稳定的入射能量降低效果。总之,氧化镱显示出作为乳霜的辐射屏蔽材料的潜力。
To ensure the safety of medical personnel in healthcare organizations, radiation-shielding materials like protective clothing are used to protect against low-dose radiation, such as scattered rays. The extremities, particularly the hands, are the most exposed to radiation. New materials that can be directly coated onto the skin would be more cost-effective, efficient, and convenient than gloves. We developed protective creams using eco-friendly shielding materials, including barium sulfate, bismuth oxide, and
ytterbium oxide, to avoid harmful effects of heavy metals like lead, and tested their skin-protective effects. Particularly, the radiation-shielding effect of
ytterbium oxide was compared with that of the other materials. As shielding material dispersion and layer thickness greatly affect the efficacy of radiation-shielding creams, we assessed dispersion in terms of the weight percentage (wt%). The effective radiation energy was reduced by 20% with a 1.0-mm increase in cream thickness.
Ytterbium oxide had a higher radiation-shielding rate than the other two materials. A 28% difference in protective effect was observed with varying wt%, and the 45 wt% cream at 63.4 keV radiation achieved a 61.3% reduction rate. Higher content led to a more stable incident energy-reducing effect. In conclusion,
ytterbium oxide shows potential as a radiation-shielding material for creams.
