We grew 1.5-in Eu doped ${\rm SrI}_{2}$ (${\rm Eu}:{\rm SrI}_{2}$) bulk single crystal by a modified vertical Bridgman (VB) method using a removable chamber and high-frequency induction heating. As-grown 1.5-in ${\rm Eu}:{\rm SrI}_{2}$ bulk single crystal had no visible crack and inclusion in the crystal. In the transmittance and $\alpha $-ray radioluminescence spectra, large absorption below 433 nm and emission peak at 433 nm were observed, respectively. Each polished ${\rm Eu}:{\rm SrI}_{2}$ specimen indicated $56 \thinspace 000 \sim 62 \thinspace 000\ \hbox{ph/MeV}$ light yield and $3.3 \sim 3.9\%$ energy resolution. The decay times of the specimens were $0.61 \sim 0.67\ \mu \hbox{s}$.
