From imaging to treatment

From imaging to treatment

Diagnostic X-rays are used to form images, so their energy is just high enough to pass through tissue and produce contrast. They are typically about 20 keV20 \text{ keV}20 keV to 150 keV150 \text{ keV}150 keV, whereas external beam radiotherapy uses much higher-energy X-rays, typically about 1 MeV1 \text{ MeV}1 MeV to 20 MeV20 \text{ MeV}20 MeV.

Step-by-step lessons on AQA A Level Physics Use of high-energy X-rays (A-level only). Each one builds up to exam-style questions. Physics is one of the most mathematically demanding A Levels -- at least 40% of the marks require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
