Radiation material science structures to fulfill their purpose, a firm understanding of the effect of radiation on materials is required in order to account for irradiation effects in design, to mitigate its effect by changing operating conditions, or to serve as a guide for creating new, more radiation-tolerant materials that can better serve their purpose. The types of radiation that can alter structural materials consist of neutrons, ions, electrons and gamma rays. All of these forms of radiation have the capability to displace atoms from their lattice sites, which is the fundamental process that drives the changes in structural metals.The inclusion of ions
Radiation-induced lumbar plexopathy limiting the mean dose to < 45 Gy. One approach to reduced levels, the plexus' mapping with other organs at risk, was clinically evaluated during the 2010s. Clinical evidence of the cause-and-effect of prevention and the management of radiation induced polyneuropathy is limited. In 2011 the National Radiation Oncology Registry (NROR) was announced by the Radiation Oncology Institute (ROI). ROI and Massachusetts General Hospital would collect efficacy and side effect information (like radiation induced neuropathy) from people who had undergone radiotherapy. In 2013 the American Society for Radiation Oncology joined the effort. Experimental approaches of RILP treatment include: Radiation-induced lumbar
