Which of the following radioisotopes will not be commonly used in the medical field? Question 14 options: Radium-226 (half-life = 1600 years) Iodine-131 (half-life = 8.0 days) Technetium-99m (half-life = 6.0 hours) Chromium-51 (half-life = 28 days)

Expert Solution

Step 1

Radioisotopes are used in various applications in the medical field, such as imaging, diagnosis, and treatment of various diseases. However, the choice of radioisotope used in medical applications is important and dependent on several factors, including the half-life of the isotope, the type of radiation emitted, and the associated radiation risk. In this context, Radium-226 is not commonly used in the medical field due to its long half-life and the associated radiation risk. In this answer, we will discuss the reasons why Radium-226 is not commonly used in medical applications and why other radioisotopes with shorter half-lives and less ionizing radiation are preferred.
