Verifikasi Keluaran Radiasi Pesawat Linac (Foton Dan Elektron) Serta 60Co Dengan TLD
Main Article Content
Abstract
60Co dalam medium Solid Water Phantom milik Rumah Sakit Pusat Angkatan Darat
(RSPAD) Gatot Soebroto. Pengukuran bertujuan untuk memperoleh informasi mengenai
keakurasiaan keluaran radiasi dengan menggunakan TLD. Pengukuran dilakukan dengan
teknik SSD 100 cm untuk pesawat Linac dan SSD 80 cm untuk 60Co pada kedalaman dosis
maksimum dengan variasi dosis 50 cGy sampai dengan 250 cGy pada luas lapangan 10 x
10 cm2. Hasil pengukuran menunjukan bahwa deviasi dosis yang diterima Solid Water
Phantom sebagai target pada kedalaman dosis maksimum untuk keluaran radiasi foton
energi 6 MV memiliki nilai deviasi dalam rentang 0,04 % - 0,46 %, keluaran radiasi foton
energi 10 MV memiliki nilai deviasi dalam rentang 0,67 % - 2,37 %, untuk keluaran radiasi
elektron energi 10 MeV memiliki nilai deviasi dalam rentang 1,03 % - 1,56 %, untuk
keluaran radiasi 60Co memiliki nilai deviasi dalam rentang 0,20 % - 0,74 %, cukup stabil
sesuai batas toleransi ≤ 5 % (dalam batas toleransi yang disyaratkan IAEA). Dari hasil ini
dapat disimpulkan bahwa kondisi pesawat Linac dan 60Co di RSPAD Gatot Soebroto
masih diterima untuk digunakan.
