Plutonium 239PU is an unstable nuclei and decays with a half-life t= 2.4 x 104 years by producing smaller nuclei including an alpha particle. Find the alpha particle flux density (number of the alpha particles per unit area per unit time) near the surface of a large plate of 239PU having thickness d =1 mm. Density of plutonium is p= 19800 kg/m³ and mass of an atom of 239P is mo = 3.84 × 10-25 kg. Ans: Pdln2=2.36x3 m-s- %3D %3D =D2.36N03 m-"s らー1 22mo
