The particle-induced depression of the superconducting critical temperature, T{sub c}, of YBa{sub 2} Cu{sub 3}O{sub 7-{delta}} is shown to be directly proportional to the nonionizing energy loss (NIEL) of primary knock-on atoms (PKAs) displaced by incident electrons, protons, and heavy ions, which cover a NIEL range of over seven orders of magnitude. Calculations of the NIEL for electrons and protons are given for YBa{sub 2}Cu{sub 3}O{sub 7} over the range 1-1000 MeV. The partition of NIEL among the element as a function of incident electron energy is discussed. For a given particle fluence {Phi}, it is concluded that dT{sub c}/d{Phi} is proportional to the average number of defects produced, is not affected by the formation of defects in cascades, and is independent of the PKA spectrum. This means that the particle-induced depression of T{sub c} can be predicted for any particle type, for any energy, and for any fluence.
