Medical History for Mrs R. Jones
Mrs Jones was admitted to hospital
with shortness of breath.
To find out more accurately the
location of the tumour, Dr Adams
carried out a CT scan.
After carrying out various tests, Dr
Adams suspected she may have lung
cancer so an x-ray was carried out.
The picture below shows Mrs Jones’
x-ray, identifying her lung tumour.
It was decided that Mrs Jones would
be a suitable candidate for radiation
therapy. This process uses gamma
rays to destroy cancer cells.
YOUR TASK
Imagine you are a radiographer.
One of your elderly patients, Mrs Jones, has to have a lot of treatment recently
and is worried that the amount of radiation could be dangerous.
Write a letter to your patient to explain:
C - How x-rays work
B - Why x-rays are more suitable for this process than other types of radiation
A - How cancer is treated using radiation
A* - Decide whether your patient is in danger of radiation poisoning from their
treatment and why/why not
You should be able to complete most of these questions using your own
knowledge and the information available on Moodle.
