Worked Solution & Example Answer:Radioactivity is used in PET scanners in hospitals - Edexcel - GCSE Physics - Question 5 - 2019 - Paper 1
Step 1
Describe one use of PET scanners in hospitals.
Answer
PET scanners are utilized primarily for diagnosing and locating tumors in patients. By using radioactive tracers, these scanners provide detailed images that help medical professionals identify the presence of cancerous cells, enabling timely and accurate treatment decisions.
Step 2
State two precautions that hospital staff should take when working with radioactivity.
Answer
- Shielding: Hospital staff should wear protective clothing and utilize lead shielding to minimize their exposure to radiation.
- Distance: Maintain a safe distance from radioactive materials and patients who have undergone procedures involving radioactivity, thereby reducing the risk of radiation exposure.
