The isotope 176Lu undergoes β- decay to 176Hf with a long half-life. From a plot of 176Hf/177Hf
(y-axis) versus 176Lu/177Hf (x-axis) for a suite of cogenetic (=related) meteorites, Patchett &
Tatsumoto (1980) obtained a 10-point isochrons with a slope of 0.0934 and an initial 176Hf/177Hf
ratio of 0.27973. The age of the meteorites is known to be 4550 Ma from independent Pb-Pb
dating. Calculate the decay constant (λ) and half-life (t1/2) of 176Lu decay

Thorium (with half-life T1/2 = 1.913 yr. and atomic mass 228.0287 u) undergoes alpha decay and produces radium (atomic mass 224.0202 u) as a daughter nucleus. (Assume the alpha particle has atomic mass 4.002603 u.) 1) What is the decay constant of thorium? (Note that the answer must be in units of hrs-1.) λ = 2) What percent of thorium is left after 200 days? 3) The energy released from the decay of 10 g of thorium is used to...

Question 75 5 pts Determine the age of the zircon mineral grain from a granite in the Sierra Nevada using the 14C to 14N method. The mineral has 5678814C atoms and 87655 14N atoms. The half life (T1/2) of this system is 5730 years. What is the age? Use the curve equation T = -1.4431n(f) 1. Determine Pi, initial parent amount (add Parent Daughter) 2.f P/Pi 3. Use the curve equation to solve for T (number of half lives elapsed)...
