Raw kaolin from Kota Tinggi, Johor, Malaysia and local industrial grade barite (BaSO 4 ) were used in this study to produce a ceramic mullite (3Al 2 O 2 2SiO 2 ) for radiation shielding materials. In this work, an attempt is made to study the potential of local minerals to be used as a shielding barrier for diagnostic radiology facilities in hospitals and medical centers in Malaysia.
