Treat the tumour
Classroom Activity for 11-14 14-16
To plan a radiotherapy treatment to a patient with a cancerous tumour in their lung.
Target the beams of high energy photons at the tumour by repositioning the beams around the linear accelerator. You can also reposition the body itself using the bed controls in the top right corner. Adjust the exposure time on each beam to ensure you've exposed the tumour to enough radiation to remove it.
Radiotherapy slowly destroys the tumour with harmful radiation. Healthy tissue is also damaged by radiation, so you have to make sure that the tumour receives the required dose without damaging the tissue surrounding it.
