Answer 1

Answer:

The iodine isotope 13153I is used in hospitals for diagnosis of thyroid function. 742 μg are ingested by a patient. The half-life the iodine isotope 13153I is 8.0207 days and mass is 130.906 u.

Part A

Determine the activity immediately after ingestion

Part B

Determine the activity 1.00 h later when the thyroid is being tested.

Part C

Determine the activity 4.5 months later. Suppose that each month has 30 days.
