Let N be the number of atoms of Cs137= 7.3*10^22 atoms. Also, let λs be the “probability of Cs137 =7.32*10^-10 /sec. ”. At this time, the product (multiplication) of N and λs is "the number of decays of 1 g of Cs137 per second", and the unit is Bq. From the above, find out how many Bq the "total amount of radioactivity when 1 g of Cs137 decays per second" is measured. (However, measurement error is not considered)
