Abstract EN

In this research some physical properties of (SBR) solutions in heptane have studied before and after irradiation γ-rays using the source ( ) of average energy (1.22 Me) with radiation dose of (255.08 Rad).The theological properties include viscosity were calculated and decrease of these values after radiation .

v60 Co mechanical properties were studied by measuring the ultrasonic velocity for different concentrations and decrease in values of absorption coeffient of ultrasonic wave of different concentration .optical properties such as absorbance and refractive index have been measured and decrease of optical properties value after radiation .
