评价给¹²⁵I放射粒子植入术后患者佩戴防辐射口罩对¹²⁵I放射粒子辐射的防护效果。

选取我院2015年12月至2017年12月因腭部腺样囊性癌行¹²⁵I放射粒子植入术治疗的患者36例，将其随机分为对照组和试验组，每组18例。对照组术后采用距离防辐射，试验组术后采用¹²⁵I放射粒子植入术后患者专用口罩，监测并比较距离两组对象0、20、50 cm的辐射剂量。

对照组与试验组植入的¹²⁵I数分别为（30±3）颗和（31±2）颗，差异无统计学意义（t=1.177，P=0.248）。试验组术后接受的辐射剂量远低于对照组，差异有统计学意义（P<0.001）。且试验组监测的辐射剂量符合国家标准规定的辐射剂量的公众限值2.5 μSv/h以下。

使用防辐射口罩可以有效降低和屏蔽手术后¹²⁵I放射性粒子对外界的放射，使患者可以正常的与外界交流和生活，促进身体恢复，提高患者满意度。

To evaluate the radiation shielding effect of ¹²⁵I radiation mask on radiation of ¹²⁵I patients after radioactive seed implantation.

From December 2015 to December 2017, 36 patients with adenoid cystic carcinoma of palate treated with ¹²⁵I radioactive seed implantation were randomly divided into control group (n=18) and experimental group (n=18) . The patients in control group were treated with distance protection and the patients in experimental group with ¹²⁵I radioactive seed implantation wore the mask. The radiation dosage of two groups of subjects with the radiation lengths of 0, 20 and 50 cm were monitored using radiation-proof apparatus.

We found that the radiation dose of mask group was significantly lower than that of the non-mask group (P<0.01) after ¹²⁵I radioactive seed implantation. After wearing the mask, the mean dose monitored after the operation was in accordance with the public limit of 2.5 μSv/h stipulated by the national standard.

The use of radiation masks can effectively reduce and shield the radiation of ¹²⁵I radioactive particles to the outside world after surgery, so the patients can communicate with the outside world and normal life, promote physical recovery, and the patient satisfaction can be improved.
