Examples

2. The relationship between cumulative skin dose and peak skin dose is highly variable, as has been demonstrated in a number of publications.
3. The relationship between cumulative skin dose and peak skin dose is highly variable, as has been demonstrated in a number of publications.
4. A typical example of this is the application of a defined thickness of bolus to a chest wall for post-mastectomy chest wall treatment, to increase the skin dose.
5. Megavoltage x-rays are preferred for treatment of deep lying tumours as they are attenuated less than lower energy photons, and will penetrate further, with a lower skin dose.
