24.3.2—That a tracer that decays by β+ decay is used in positron emission

recall that a tracer that decays by β+ decay is used in positron emission tomography (PET scanning).

Use —that a tracer that decays by β+ decay is used in positron emission to connect the rule to the data and decision in the question.

This matters because —that a tracer that decays by β+ decay is used in positron emission determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —that a tracer that decays by β+ decay is used in positron emission to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —That a tracer that decays by β+ decay is used in positron emission is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
