Morphology

radioactive + iodine + uptake + test

The phrase denotes a test measuring how much radioactive iodine is taken up (absorbed), so the overall meaning is directly compositional from 'radioactive' + 'iodine' + 'uptake' + 'test'. Although the context is medical and slightly technical, the constituent meanings combine in a straightforward, predictable way that a B1 learner who knows the component words can infer.

Etymology

Radioactive iodine uptake test comes from a simple picture: doctors give the thyroid a very small, safe amount of radioactive iodine that shows on a scan and then check the gland's uptake. So the test 'measures' how active the thyroid is.
