- At t = 0 s, you have a pure sample of an unknown substance. At t = 948 s, 36.8% of the substance remains. Determine the decay constant and what t will be when 12% of the substance remains. λ = s1 t=At t = 0 we begin to observe two identical radioactive nuclei that have a half-life of 5 min. At t = 1 min, one of the nuclei decays. Does that event increase or decrease the chance that the second nucleus will decay in the next 4 min, or is there no effect on the second nucleus? (Are the events cause and effect, or random?)A certain particle has a half-life of 179. s. What is the decay constant, in s-1?
- An old campfire is uncovered during an archaeological dig. Its charcoal is found to contain less than 1/1000 the normal amount of 14C. Find the minimum age (in years) of the charcoal. Carbon-14 has a half-life of 5730 years which means half of it will be gone after 5730 years. You may find the equality 210 = 1024 to be useful.The isotope cadmium-122* undergoes gamma decay. Write the reaction equation, and determine the identity of the daughter nucleus.The uranium decay series from U-238 to stable lead (Pb-206) is: U → Th → *Pa → U → 0Th → Ra → Rn → 18Th → Pb → Bi 238U 234TH 226 → Po 92 92 210Pb → 210 Bi → 210P0 → 206Pb 83 84 Of the 15 nuclei from U-238 to Pb-206, list those radionuclides that are alpha-particle emitters, and those that are beta-particle emitters. State your reasons.
- Neutron probes are used in agronomy to measure the moisture content of soil. A pellet of 241 Am emits alpha particles that cause a beryllium disk to emit neutrons. These neutrons move out into the soil where they are reflected back into the probe by the hydrogen nuclei in water. The neutron count is thus indicative of the moisture content near the probe. What is the energy of the alpha particle emitted by the 241^Am? Answer in megaelectron volts66/28Ni (mass = 65.929 1 u) undergoes beta decay to 56/29 (mass = 65.928 9 u). (a) Write the complete decay formula for this process. (b) Find the maximum kinetic energy of the emerging electrons.
