Question

Bragg peak effect pronounced in:

• A. X ray
• B. Proton
• C. Neutron
• D. Electron

Answer 1

The Correct Option is B

In the context of radiotherapy and radiodiagnosis, the Bragg peak is a term that refers to the phenomenon where charged particles, such as protons, deposit a maximum amount of energy at a specific point in their path before quickly losing energy. This effect is particularly noticeable with protons, making them highly effective in targeting tumors with minimal damage to surrounding healthy tissue.

This peak is characterized by a sharp increase in energy deposition just before the particles come to a halt, allowing for precise control over the radiation dose delivery. The other options mentioned, such as X-rays, neutrons, and electrons, do not exhibit a similar pronounced Bragg peak as protons do:

• X-rays: These are electromagnetic waves and do not exhibit a Bragg peak. Instead, they have an exponential attenuation as they pass through tissue.
• Neutrons: Although they can be used in radiotherapy, they do not produce a pronounced Bragg peak like protons.
• Electrons: These particles have an energy distribution that lacks the distinct Bragg peak, resulting in less control over energy deposition depth compared to protons.

Therefore, the Bragg peak effect is pronounced in protons, enabling them to deliver targeted therapy in cancer treatments.
