Abstract


Latar Belakang: Quality Control (QC) pada apron wajib dilakukan satu tahun sekali. Hal ini bertujuan untuk memastikan keamanan pada pekerja radiasi sebelum melakukan prosedur pemeriksaan radiologi sehingga penerimaan dosis radiasi tidak melebihi 20 mSv/ tahun.

Tujuan: Menganalisis efektivitas penggunaan apron 0.35 mmPb untuk melindungi pekerja radiasi pada pemeriksaan radiografi.

Metode: Penelitian ini dilakukan di laboratorium Jurusan Teknik Radiodiagnostik dan Radioterapi, Poltekkes Kemenkes Jakarta II. Prosedur yang dilakukan pada penelitian adalah dengan simulasi apabila pekerja menerima paparan radiasi primer dan sekunder pada jarak 100 cm dengan rentang faktor eksposi 45-100kVp. Apron yang digunakan berbahan timbal (Pb) dengan ketebalan 0.35 mmPb dan, untuk pekerja radiasi, diganti dengan menggunakan pantom anthorophomorpic. Penggunaan luas lapangan sesuai kondisi klinis yaitu 18 cm x 24 cm, 43 cm x 35 cm, dan kemudian dilakukan analisis efektivitas apron Pb terhadap perubahan faktor eksposi.

Hasil: Hasil penelitian menunjukkan bahwa efektivitas penggunaan apron 0.35 mmPb pada rentang tegangan tabung 45-100kVp untuk kedua penggunaan luas lapangan memiliki nilai persentasi yang sama 99.9-93%.

Kesimpulan: Peningkatan tegangan tabung menyebabkan terjadinya penurunan atenuasi apron Pb.
