Abstract

With recent renewal interest in survivability, radiation hardening against cold or hot x-ray as well as high power laser energy among defense companies and military communities, radiation shielding of military equipment becomes an imperative task and requirement. Materials used in radiation shielding is one way to go to protect any vulnerable digital circuits in form of an integrated circuit, and consequently selecting of such ICs for a radiation environment also becomes a necessity as part of survivability requirements. Thermomechanical properties of materials as part of shielding are also going to play a huge role as part of protection of these ICs as well. With most countries getting involved with their nuclear arsenal development, protection of our assets in space or on ground such as electric circuits and grids is another issue that we need to think about to survive a nuclear burst both Endo and Exo-atmospheric circumstance. The effects of nuclear explosions produce both immediate and delayed destructive effects, that requires choice of right and proper protective materials for ICs to be shielded and survivable in such radiation environment driven by a nuclear weapon burst. Nuclear weapon effects in term of blast, thermal radiation, electromagnetic pulse, and prompt ionizing radiation, etc. are part of concerns for choosing the proper materials. Radiation shielding is based on the principle of attenuation, which is the ability to reduce a waves or ray’s effect by blocking or bouncing particles through a barrier material. This short review is discussing different holistic issues in respect to selected materials and integrated circuits in respect to survivability and shielding within a radiation environment, either man-made or natural.
