dc.description.abstractABSTRACT VENANDA AGUSTINA. Synthesis of Neutron Radiation Shields Based on Concrete With Variations of Sand Types. Supervised by MOHAMMAD NUR INDRO, DJAMIL HUSIN and IWAN SUMIRAT. Neutron radiation is ionizing radiation which has a high penetrating power. So a radiation shield is needed to reduce the danger from neutron radiation. In this study, a neutron radiation shield was made from concrete with 3 different types of sand, namely lukulo sand, white bangka sand and black bangka sand. Concrete as a shield for neutron radiation is tested for its absorption ability using the film method. This experiment also uses Energy-dispersive X-ray spectroscopy (EDS) for elemental analysis. The test results show that the white bangka sand concrete has a good performance as a neutron radiation shield because it has a high attenuation coefficient and a high neutron cross-section. The linear attenuation coefficient of lukulo sand concrete, white bangka sand concrete and black bangka sand concrete were 0.182 cm-1, 0.548 cm-1 and 0.430 cm-1, respectively. The cross-section of the largest neutron is owned by the white bangka sand, then the black bangka sand and lukulo sand. Keywords: Attenuation coefficient, Concrete, Film method, Neutron radiation, Neutron radiation shieldingid
dc.description.abstractRadiasi neutron merupakan radiasi pengion yang memiliki daya tembus yang tinggi. Sehingga diperlukan perisai radiasi untuk mengurangi bahaya dari radiasi neutron. Pada penelitian ini dibuat perisai radiasi neutron dari beton dengan 3 jenis pasir berbeda yaitu pasir lukulo, pasir putih bangka dan pasir hitam bangka. Beton sebagai perisai radiasi neutron di uji kemampuan serapannya dengan menggunakan metode film. Eksperimen ini juga menggunakan Energy-dispersive X-ray spectroscopy (EDS) untuk analisis unsur. Hasil pengujian menunjukan bahwa beton dari pasir putih bangka memiliki kinerja yang baik sebagai perisai radiasi neutron karena memiliki nilai koefisien atenuasi yang tinggi serta tampang lintang neutron yang tinggi. Koefisien atenuasi linear dari beton pasir lukulo, beton pasir putih bangka dan beton pasir hitam bangka berturut-turut yaitu 0.182 cm-1, 0.548 cm-1 dan 0.430 cm-1. Tampang lintang neutron dari yang terbesar dimiliki pasir putih bangka, kemudian pasir hitam bangka dan pasir lukulo.
