Thus, if N is reasonably large, half of the original nuclei decay in a time of one half-life. If an individual nucleus makes it through that time, it still has a 50% chance of surviving through another half-life. kier boiling processWebSeveral tons of radioactive waste, with a radioactivity (intensity) of 50 Ci / kg and half-life ( T 1/2?) of 49 years, is stored in a storage facility with a designated safe zone radius of 80 km.A) What will be the intensity or radioactivity after 50 years at 6 … kier cactus leather tote

"WebThe relationship between the decay constant λ and the half-life t1 / 2 is λ = ln (2) t1/2 ≈ 0.693 t1 / 2. 31.37 To see how the number of nuclei declines to half its original value in one half-life, let t = t1 / 2 in the exponential in the equation N = N0e − λt. This gives N = N0e − λt = N0e−0.693 = 0.500N0. " - If t1/2 is the half life
