Question: 4) Sodium-22 (Na-22) Is Radioactive And Decays By Beta Plus Decay Mode. The Half-life Is 2.603 Years. (a) Calculate The Binding Energy Per Nucleon For Sodium-22. (b) Write The Reaction For The Decay, Calculate For The Decay Reactio 22 11 Na → 22 10 Ne + 0 + 1 e + + ν; 207 83 Bi + 0-1 e-→ 207 82 Pb + ν; 238 92 U → 234 90 Th + 4 2 He; Given the masses of relevant atoms and the mass change criteria for beta decay, we calculate: Δm = m[24 12 Mg] - m[24 11 Na] Δm = 23.9850419 u - 23.990963 u = -0.0059211 u ΔE = (-0.0059211 u)(931.494 MeV / u) = -5.515 MeV Sodium-22 | Na | CID 6328543 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards The radionuclide {sup 22}Na is a potential astronomical observable that is expected to be produced in classical novae in quantities that depend on the thermonuclear rate of the {sup 22}Na(p,{gamma Near a 22 Na source, beta radiation doses can be much higher than the gamma dose. Shielding the high energy gamma radiation with lead will also stop all of the ß's and Bremstralung radiation. Always store 22 Na vials in lead containers or behind shields.
