Use the nuclide table from http://atom.kaeri.re.kr/ton/nuc7.html to find the decay of 238U and its half-life. Compare the half-lives of 238U and its daughter nuclide and define the condition for secular equilibrium. Calculate the molar concentration of the daughter nuclide at secular equilibrium if the activity of 238U is 2.3 dpm/kg.
