"Two scientists connected with Brunel University update their 1993 handbook for physicists and engineers. The original goal was to compile information from space environments, and those still dominate, though the environments of nuclear reactors, radiation processing, weapons, high-energy accelerators, and controlled fusion are also considered. Among other topics are measurement, responses of materials and devices, metal-oxide-semiconductor devices, bipolar transistors and integrated circuits, diodes, solar cells and optoelectronics, power semiconductors, and polymers and other organics. Biological effects are not covered. Dose units cited tend to be those used in practice--usually rad and rem--rather than the newer Gray and Sievert."--SciTech Book News
