Find the time for 2.8 micro curies in the patient's thyroid.
Answer to Problem 55E
Explanation of Solution
Given information:
Nuclear medicine technologists use the iodine isotope I-131, with a half-life of 8 days, to check thyroid function of patients. After ingesting a tablet containing the iodine, the isotopes collect in a patient's thyroid, and a special camera is used to view its function. Suppose a patient ingests a tablet containing 9 micro curies of I-131. To the nearest hour, A micro curie is a measure of radioactive.
Calculation:
Consider, the formula for time period,
Here
Conclude that the time needed to get to
Hence, the time for 2.8 micro curies in the patient's thyroid is
