The tsunami that followed left thousands of people dead and triggered a meltdown at the Fukushima Daiichi Nuclear Power Plant, releasing radioactive isotopes 137Cs and 134Cs, among others, into the atmosphere and into the Pacific Ocean. By December 2015 (about 1,730 days after the meltdown), contaminated seawater reached the US west coast with maximum Cs activities (including both isotopes) per cubic meter of seawater reaching 11.0 Bq/m3, more than 500 times below the US government safety limits for drinking water. The half-lives of 137Cs and 134Cs are 1.10 ✕ 104 days and 734 days, respectively. Calculate the number of 137Cs and 134Cs nuclei in the 1.00 m3 seawater sample, assuming 137Cs and 134Cs were originally released in equal amounts.
