A radiation oncologist treats cancer with two species of radioactive nuclei, X and Y. The initial number of nuclei for each species (at t = 0) is No. At t = 100 s, the oncologist observes that Nx = 100 Ny. If Tx = 2 Ty, the value of ty (in s) is: (Recall that T = (1/A) and 1 Ci = 3.7 x 10¹0 Bq) 0.50 4,07 36.36 61.77 10.86
