Radiation Shielding for Fusion Reactors

Radiation shielding requirements for fusion reactors present different problems than those for fission reactors and accelerators. Fusion devices, particularly tokamak reactors, are complicated by geometry constraints that complicate disposition of fully effective shielding. This paper reviews some of these shielding issues and suggested solutions for optimizing the machine and biological shield...

New Methods Developed for Shielding Material Characterization

− The theory of electromagnetic shielding is based on the waves equations describing the behavior of electromagnetic field in substance and also boundary phenomena by means of Fresnel’s reflection and transmission coefficients. The interaction between electromagnetic radiation and infinite plane shield having finite thickness d, placed in free space in plane waves region depends of material/shi...

Radiation shielding technology.

An historical review of the development of shielding techniques for indirectly ionizing radiation is presented, along with a summary of techniques at various levels of sophistication for shielding design and analysis.

Shielding of Gamma Radiation

In the discussion that follows, we assume that gamma rays are the radiation of interest. The principles discussed also apply to monoenergetic x rays; in many cases of concern in x-ray shielding, however, the photons are produced in the bremsstrahlung process that yields a wide and continuous distribution of photon energies. Specialized shielding approaches have been developed to carry out shiel...
