Analisa Kualitas Sinar-X Pada Variasi Ketebalan Filter Aluminium Terhadap Dosis Efektif
Main Article Content
Abstract
untuk mengetahui kualitas sinar-x pada variasi penggunaan filter aluminium terhadap dosis
efektif dengan menggunakan lembaran Alumunium yang mempunyai ketebalan bervariasi
mulai dari variasi tanpa filter tambahan, dengan filter 0,5 mm Al,1 mm Al,1,5 mm Al,2
mm Al, 2,5 mm Al, dan 3 mm Al. Pengukuran dilakukan pada 3 kondisi tegangan yaitu 55
kV, 60 kV dan 65 kV. Dari hasil analisa pengujian keluaran pesawat sinar-x didapatkan
keluaran sinar-x yang tidak sesuai tetapi masih dalam batas toleransi. Dan setelah dilakukan
perhitungan nilai rata-rata dosis efektif pada pemeriksaan radiografi tulang panggul
didapatkan nilai rata-rata dosis efektifnya adalah 0.069 mSv, jadi nilai rata-rata dosis efektif
pada penelitian ini lebih kecil dari nilai rata-rata dosis efektif pada pemeriksaan radiografi
tulang panggul diseluruh dunia berdasarkan laporan UNSCEAR 2000 yaitu 0.74 mSv.
