The ultrasonic velocities were measured in bismuth lead borosilicate and barium lead borosilicate glass sample of different compositions before and after irradiation with -rays. Measurements were carried out at room temperature and 4 MHz frequency using Ultrasonic technique. The ultrasonic velocities data of glass sample have been used to find the elastic modulus and micro-hardness. Densities of the glass samples were measured by Archimedes’ principle using n-hexen as immersion liquid. It was found ultrasonic velocity, elastic modulus and micro-hardness increase with increasing bismuth oxide content, barium oxide content and increasing – radiation doses (3-12 Gy)
