A breeder reactor converts relatively stable uranium 238 into the isotope plu- tonium 239. After 15 years it is determined that 0:043% of the initial amount Ao of plutonium has disintegrated. Find the half life of this isotope if the rate of disintegration is proportional to the amount of remaining.
