Chapter 0, Problem 24(choose chapter or problem)
After a spill of radioactive iodine, measurements showed the ambient radiation levels at the site of the spill to be four times the maximum acceptable limit. The level of radiation from an iodine source decreases according to the formula R(t) = R0e0.004t where R is the radiation level (in millirems/hour) at time t in hours and R0 is the initial radiation level (at t = 0). (a) How long will it take for the site to reach an acceptable level of radiation? (b) How much total radiation (in millirems) will have been emitted by that time, assuming the maximum acceptable limit is 0.6 millirems/hour?
