An archaeologist sometime in the future analyzes the iron used in an old building. The iron contains tiny amouns of nickel-63, with a half-life of 92 years. On the basis of the amount of nickel-63 and its decay products found, it is estimated that about 0.78% (1/128) of the original nickel-63 remains. How many half lives have passed to leave only 0.78% (1/128) of the original amount? If the building was constructed in 1980, in what year did the archaeologist make the discovery?
