Why is it safe to use radioisotopes for diagnosing medical problems?

Radioisotopes are considered safe for medical diagnostics because they are used in very small doses, minimizing exposure to radiation. They emit low levels of radiation that can be effectively controlled and monitored during procedures such as imaging. Additionally, the radioisotopes used typically have short half-lives, meaning they decay quickly and are eliminated from the body, further reducing potential risks. Overall, the benefits of accurate diagnosis often outweigh the minimal risks associated with their use.
