A nuclear technician was accidentally exposed to potassium-42 while doing brain scans for possible tumors. The error was not discovered until 36 hh later when the activity of the potassium-42 sample was 4.0 μCμC. If potassium-42 has a half-life of 12 hh, what was the activity of the sample at the time the technician was exposed?
