Abstract

Telah dilakukan penelitian tentang estimasi dosis radiasi yang diterima lensa mata menggunakan TLD-100 pada 20 pasien brain scanning CT-Scan di Instalasi Radiologi RSUP Dr. M. Djamil Kota Padang. Pengukuran dilakukan dengan memasang dosimeter termoluminesensi-100 (TLD-100) pada holder TLD mata ke kepala pasien dengan posisi dekat lensa mata. Data yang telah tersimpan pada TLD-100 kemudian dibaca menggunakan TLD reader. Data diolah menggunakan Microsoft Excel dan Statistical Product and Service Solutions (SPSS). Hasil pengukuran dosis radiasi yang diterima lensa mata pasien berada di antara 27,90 mGy hingga 47,55 mGy. Dari hasil pengukuran dapat diketahui bahwa tidak ada nilai dosis radiasi yang melebihi Nilai Batas Dosis (NBD) kerusakan lensa mata yang ditetapkan oleh Perka BAPETEN Nomor 4 Tahun 2013, karakterisasi perangkap radiasi yang digunakan memiliki pola kurva pancar yang sama untuk pasien 1-20. Berdasarkan perhitungan statistik, arus tabung memiliki pengaruh terhadap dosis radiasi lensa mata sedangkan waktu penyinaran dan umur pasien tidak memiliki pengaruh terhadap dosis radiasi lensa mata.

 

The reasearch estimated dose of radiation received the lens of the eye used TLD-100 on 20 brain scanning CT-Scan patients in Radiology Installation of RSUP Dr. M. Djamil Padang. Measurement was done using Thermoluminescence Dosemeter-100 (TLD-100) which in TLD eye holder at eye lens of brain scanning patiens. The data that has been stored in TLD-100 then read use TLD reader. Data was processed using Microsoft Excel and dan Statistical Product and Service Solutions (SPSS). Research result of radiation dose are eye lens accept radiation dose range 27,90 mGy till 47,55 mGy. From the measurement result, there is no radiation dose that exceed the threshold value for eye lens damage set by Perka BAPETEN No. 4 at 2013, the radiation trap characterizations used have same pattern for patien 1-20. Based on statistic, the current tube have effect to the radiation dose while time of expose and age of patient have not effect to the radiation dose of eye lens brain scanning patient.
