Question

In111 delivers a lower radiation dose to the patient than Ga67 because it only has one gamma emission, whereas Ga67 has four.

a. true
b. false

Answer 1

In111 delivers a lower radiation dose to the patient than Ga67 because it only has one gamma emission, whereas Ga67 has four.

Step-by-step explanation:

In111 delivers a lower radiation dose to the patient than Ga67 because it only has one gamma emission, whereas Ga67 has four.

The number of gamma emissions from an isotope can affect the radiation dose it delivers. In111 emits one gamma ray during decay, while Ga67 emits four gamma rays. Gamma rays are a type of ionizing radiation that can penetrate the body and cause damage to cells. Therefore, an isotope with fewer gamma emissions, like In111, will deliver a lower radiation dose to the patient.

For example, if we consider a patient receiving a single dose of each isotope, In111 will expose the patient to one gamma ray, while Ga67 will expose the patient to four gamma rays. This means that In111 delivers a lower radiation dose to the patient compared to Ga67.
