The half life of radium-226 is 1620 years. Initially, there are 2-grams in a sample. (a) Half life decay can be modeled by an exponential function: N(t) = N0 ekt. Use the growth equation, kt = ln (N1/N0) to find k. (b) How many grams remain after 10 years? (c) How long will it take for 80% of the 2 grams to decay?
