Suppose an unknown radioactive substance produces 6400 counts per minute on a Geiger counter at a certain time, and only 200 counts per minute 12 days later. Assuming that the amount of radioactive substance is proportional to the number of counts per minute, determine the half-life of the radioactive substance. The radioactive substance has a half-life of days.
