A medical physicist prepares a tracer dose of Fluorine-18, a positron emitter used in oncology PET scans, with an initial activity of 760 MBq760\text{ MBq}760 MBq.
The half-life of Fluorine-18 is 110 minutes110\text{ minutes}110 minutes.
Calculate the activity of this tracer dose remaining after a period of 110 minutes110\text{ minutes}110 minutes.
Practise Edexcel GCSE Physics Radioactive decay, half-life and uses with exam-style questions for Foundation and Higher tier. 100 questions, matched to the Edexcel GCSE Physics (1PH0) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
