Question 3

Iodine-131 is a radioactive isotope widely used in nuclear medicine to treat thyroid cancer. It has a half-life of 8 days.

A therapeutic dose of Iodine-131 was prepared at a manufacturing facility, but due to a logistics delay, the activity of the sample decreased from $kBq1200\text{ kBq}$ to $kBq75\text{ kBq}$ by the time it was delivered to the oncology clinic.

Determine the time, in days, that passed during this delivery delay.
