In modern radiotherapy, superconducting wire coils are used to create magnetic fields that focus particle beams in order to deliver the maximum dose of ionizing radiation to a tumor site while minimizing the destruction of healthy tissue. For which of the following types of radiation would this technique NOT be useful?Question 10 Answer Choices A. Alpha particles B. Proton beams C. Gamma photons D. Beta particles
Question
In modern radiotherapy, superconducting wire coils are used to create magnetic fields that focus particle beams in order to deliver the maximum dose of ionizing radiation to a tumor site while minimizing the destruction of healthy tissue. For which of the following types of radiation would this technique NOT be useful?Question 10 Answer Choices A. Alpha particles B. Proton beams C. Gamma photons D. Beta particles
Solution
This technique would not be useful for Gamma photons. The reason is that Gamma photons are uncharged and therefore are not influenced by magnetic fields. The other types of radiation listed (Alpha particles, Proton beams, and Beta particles) are all charged particles and can be focused using magnetic fields.
