The nuclear radiations have a number of applications in various fields of science and technology but at the same time these radiations have many hazardous effects to mankind. For this it is must that the radiations should properly be shielded. To explore the possibility of use of flyash (a waste material as a resourceful material) as gamma radiation shielding material it is necessary to study the basic interactions of gamma radiations in flyash materials. In the present book, the preparation and gamma radiation shielding properties of barium borate flyash glasses, zinc doped lead borate...
