Low temperature properties of transuranic and oter heavy metals. by Wigley, D

“…This self heat is a result of the absorption by the crystal lattice of the kinetic energies of the alpha particle and the recoil nucleus. At room temperature this has little or no effect on the physical properties of these metals but at low temperatures it is possible for the defects produced in the lattice to remain in equilibrium with their surroundings.…”
