Moment of Inertia Disc Thickness Ratio

A circular disc has radius R₁ and thickness T₁. Another circular disc made of the same material has radius R₂ and thickness T₂. If the moment of inertia of both discs are same and $\frac{{{R_1}}}{{{R_2}}} = 2$ then $\frac{{{T_1}}}{{{T_2}}} = \frac{1}{\alpha }$ . The value of α is ____.
