Which of the radioactive isotopes is used for temperature control in blood disease?

Options

A. `P^(32)`
B. `H^(3)`
C. `Rn^(233)`
D. `I^(131)`

Answer

To solve the question of which radioactive isotope is used for temperature control in blood disease, we can follow these steps:

### Step 1: Understand the Question
The question asks for a specific radioactive isotope that is used for temperature control in a blood disease. The context suggests that we are looking for a treatment related to blood disorders.

### Step 2: Identify the Blood Disease
The video transcript mentions leukemia as a blood disease. Leukemia is a type of cancer that affects blood cells, particularly white blood cells.

### Step 3: Review the Options
The options provided are:
- A) Phosphorus
- B) Hydrogen
- C) Radon
- D) Iodine

### Step 4: Research the Isotopes
We need to determine which of these isotopes is commonly used in the treatment of leukemia:
- **Phosphorus-32 (P-32)**: This isotope is known for its use in the treatment of certain types of leukemia. It helps in targeting and destroying cancerous cells.
- **Hydrogen**: Not typically used in blood disease treatments.
- **Radon**: Primarily used in radiation therapy for cancer but not specifically for blood diseases.
- **Iodine**: Commonly used in thyroid treatments but not for leukemia.

### Step 5: Conclusion
Based on the information gathered, Phosphorus-32 is the radioactive isotope used for temperature control in blood disease, specifically in the treatment of leukemia.

### Final Answer
The correct answer is **Phosphorus-32 (P-32)**.
