UJI MIKRODOSIMETRI DARI BERKAS NEUTRON DOUBLE LAYER BAM SHAPING ASSEMBLY MENGGUNAKANMETODE MONTE CARLO
Abstract
Double Layer Beam Shaping Assembly (DLBSA) adalah sistem pengolah berkas neutron cepat menjadi neutron epitermal. DLBSA telah menghasilkan berkas neutron epitermal sesuai standar IAEA. Namun DLBSA belum dilakukan uji mikrodosimetri guna mengetahui efek dan respon biologi pada tingkat sel. Penelitian ini bertujuan untuk menentukan parameter mikrodosimetri yaitu Linear Energy Transfer (LET) dan Relative Biological Effectiveness (RBE). Uji paremeter mikrodosimetri dilakukan menggunakan model mikrosel yang diinteraksikan dengan neutron dari DLBSA. Perhitungan parameter mikrodosimetri dilakukan menggunakan program berbasis monte carlo yaitu Particle Heavy Ion Transport System ( PHITS). Hasil uji mikrodosimetri diperoleh nilai LET dari berkas neutron DLBSA sebesar 100 KeV dan nilai RBE 2,56.
