If one liter of milk contaminated with iodine 131 gives a count rate of 400 counts per second how long will it take for the count rate to fall to 25 counts per second answer in days?

It takes 4 half-lives for something with 400 cps to decay to 25 cps. The half-life of 131I is 8.0252 days, so it would take four times that, or 32.1008 days for this to happen.
