Yazarlar, hastanemiz Radyasyon Güvenliği Komitesi ile işbirliği içerisinde gerçekleştirilen bu çalışmada floroskopi cihazının kullanımını izin veren Radyoloji AD’ına teşekkürü bir borç bilir.
Introduction: Lead protective apparels such as lead aprons, thyroid shields, and gonadal shielding are being used frequently for personal protection from radiation. These lead protectives may also be damaged frequently because of the usage and storage conditions. Therefore, the quality control of lead protective apparels which are performed once a year and the determination of damaged and risky ones are of great importance in the personal protection of radiation workers. In this study, it was aimed to determine the reject criteria by identifying damaged lead protective apparels.
Material and Method: In this study, the numbers of tears, the total area of these tears, % shielding effect of x-rays and effective dose values were determined by the quality control inspection with the assistance of fluoroscopy of 167 lead protectives which were used in our hospital. Based on the data obtained, damaged and risky lead protectives were determined. In addition to this, the criteria rejection of the damaged lead clothing according to the literature have been defined for the protection radiation purposes.
Results: According to the literature, the rejection criteria were determined as 10 cm2 and higher of the hole/tear area, for percent transmission value %5 and higher, and the effective dose value of 0,4 mSv. According to the damage assessment quality control study performed with these waste criteria, 7,8% of the lead shields were determined as waste and 12,8% as risky.
Conclusion: Criteria have been set for the damaging decision of the lead protective apparels which have high cost and radiation protection. Removal of damaged lead protective clothes depending on waste criteria, it also prevents unnecessary lead apron waste.
