Günümüzde, beta yayıcı radyonüklidleri içeren radyoterapi yöntemleri yaygın olarak kullanılmakta ve araştırılmaktadır. Tedavinin başarısı, belirlenen tümör alanına, hesaplanan radyasyonu doğru dozda vermekle ilişkilidir. Bu aşamada kişiye özgü dozun hesaplanması ve doz hesaplama yöntemi önem kazanmaktadır. Bu çalışmada, saf beta yayıcı İtriyum 90 (90Y) noktasal kaynağının, su ve akciğer fantomu içerisindeki radyal doz dağılımı Geant4 tabanlı GAMOS Monte Carlo yöntemi ile hesaplanmıştır. Elde edilen sonuçlar International Committee for Radiological Units (ICRU) de yayınlanan referans dozimetrik veriler ile karşılaştırılmış ve uyumlu olduğu görülmüştür.
