In AQA A-level Physics medical physics, which option best applies safety judgement to Calculate activity changes using half-life.?.
- A.It links safety judgement to Calculate activity changes using half-life. in Half-life in medicine.
- B.It describes the equipment only, without applying Calculate activity changes using half-life..
- C.It gives a general medical claim without using the relevant physics evidence.
- D.It confuses the patient outcome with the physical quantity being measured.
Model answer
What a good answer should say
- The correct option is It links safety judgement to Calculate activity changes using half-life.
- in Half-life in medicine.
