Unformatted text preview: t t = ln 0 . 02 . 000123776 31 , 606 (years) . 27. The element Hh decays according to the general law of a radioactive decay, which is described by (3.2) (this time, with t measured in years). Since the initial mass of Hh is m = 1 kg and the decay constant k = k Hh = 2 / yr, we get Hh( t ) = e k Hh t = e 2 t . (3.3) or It, the process is more complicated: it has an incoming mass from the decay of Hh and, at the same, looses its mass decaying to Bu. (This process is very similar to brine solution 114...
