In this study, radon concentration of 2D Titanium Carbide MXene Ti3 C2 was studied by using an established radon monitor. A layered MAX phase of Ti3 AlC2 was synthesized through pressureless sintering (PLS) the initial powder of TiH2 /Al/C without preliminary dehydrogenation under argon atmosphere at 1350 ˚C. An elegant exfoliation approach was used to eliminates Al from its precursor to form a layered-structure of Ti3 C2. Morphological and structural properties of this 2D material also studied. SEM images shows two types of morphology which is a layer of Ti3 C2 and the agglomerates Al2 O3 with graphite. XRD pattern reveals three phases in this material which is a rhombohedral Al2 O3, rhombohedral graphite and rhombohedral Ti3 C2 phases. Radon concentration for this material for five consecutive days explains the radiation level of this material is under the suggestion value from US Environmental Protection Agency (EPA).
