Which of the actinoids is used in the treatment of cancer? |
Plutonium Uranium Curium Thorium |
Thorium |
The correct answer is option 4. Thorium. Out of the listed actinoids, Thorium (Th) is the one used in the treatment of cancer. Here's a breakdown of the other options: Plutonium (Pu): This radioactive element is primarily used in nuclear weapons and has no known medical applications. Uranium (U): While some isotopes of uranium have been explored for potential medical uses, they are not typically used in cancer treatment due to their high radioactivity. Curium (Cm): This radioactive element also has no known medical applications. It's important to note that Thorium's use in cancer treatment is currently limited and involves ongoing research. It is not a widely used or established treatment option yet. Additionally, thorium and its compounds can be radioactive and require careful handling due to potential health risks. |
