What is the main purpose of using shielding in radiation therapy?

The main purpose of using shielding in radiation therapy is to protect healthy tissues and organs from unnecessary radiation exposure. Radiation therapy targets cancerous cells, but it can also inadvertently affect surrounding healthy cells. Shielding materials are strategically positioned to absorb or deflect radiation, minimizing its impact on non-targeted areas. This is crucial not only for reducing side effects and potential damage to healthy tissues but also for improving the overall safety and effectiveness of the treatment.

While enhancing the effectiveness of the treatment is important, that objective is typically achieved through precise targeting of the radiation rather than through shielding alone. Patient comfort is a separate consideration and is generally addressed through techniques unrelated to radiation dosage or shielding. Lastly, although shielding may have implications for radiation dose calculations, its primary role is not to assist in calculating doses but to physically protect healthy tissues.
