Ionizing radiation through the photoelectric effect and the Compton effect. Either of those interactions will cause the ejection of an electron from an atom at relativistic speeds, turning that electron into a beta particle (secondary beta particle) that will ionize many other atoms. Since most of the affected atoms are ionized directly by the secondary beta particles, photons are called indirectly ionizing radiation. Photon radiation is called gamma rays if produced by a nuclear reaction, subatomic particle decay, or radioactive decay within the nucleus. It is otherwise called x-rays if produced outside the nucleus. The generic term photon is therefore used to
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
