At an archaeological site, several well- preserved items made from wood were found. The carbon-14 present had an activity (rate of decay) of 12.3 decay events per minute. Living material exhibits an activity of 15.4 decay events per minute. Radioactive decay is a first order process. The half life of 14C is 5730 years. Determine the approximate age of the items in years.

. Let's apply the results of Problem 2 to potassium-argon dating frequently used to date sedimentary rocks. Potassium-40 decays by two different paths: electron emission electron capture where conversion to Ca occurs 89.1% of the time, and to Ar 10.9% of the time. The overall half-life for the decay of potassium-40 is 1.248 × 10⁹ years. Estimate the age of sedimentary rocks with an argon-40 to potassium-40 ratio of 1.02 %. 40 19K 140 Ca 40K 240 Ar 19 18-
