Title

STUDY OF GAMMA RADIATION INTERACTION CROSS-SECTION WITH HIGH ‘Z’AND HIGH DENSITY MATERIALS

Abstract

The interaction of gamma radiation with matter is an interesting and useful subject to study. The energy range of gamma radiation is found to be around few KeV to GeV. Since being highly energetic the interaction of gamma radiation with matter is quite different than the charge particles. By having much knowledge about this subject we can study the most of the cosmic activities like Gamma ray bubble, Gamma ray bursts etc. This study is also useful in medical applications, experimental physics, reactor and particle physics for shielding purpose. In the present work we have studied the atomic interaction cross-section, mean free path,linear absorption coefficient and mass absorption coefficientof gamma radiations of different energies. For interaction purpose we have selected Lead and Mercury which are high ‘Z’ and high densitymaterials.In the present work,the gamma ray spectra were analyzed with help ofNaI (Tl) gamma ray spectrometer coupled to the8K M.C.A. and computer. The values of atomic interaction cross-section for 511KeV, 662KeV,1170KeV and 1330KeV gamma energies with Lead are found to be 4.52 ×10-23 cm2,3.06 ×10-23 cm2,1.75×10-23 cm2and 1.72×10-23 respectively.The values of atomic interaction cross-section for 511KeV, 662KeV, 1170KeV and 1330KeV gamma energies with Mercury are found to be 4.91 ×10-23 cm2, 3.18 ×10-23cm2 ,1.62×10-23cm2 and 1.58×10-23cm2 respectively. The values of mean free path for 511KeV, 662KeV,1170KeV and 1330KeV gamma energies for Lead are found to be 0.67cm, 0.99cm,1.73 cm and 1.76 cmrespectively.The values of mean free path for 511KeV, 662KeV,1170KeV and 1330KeV gamma energies for Mercury are found to be 0.5cm, 0.77cm, 1.51cm and 1.55cm respectively. Present study indicates that for low energies; 511KeV and 662KeV, Mercury is found to be better absorber for gamma radiations whereas for high energies; 1170KeV and 1330KeV, Lead is found to be better absorber as compared to Mercury.
