Valency of iron in FeCl2and FeCl3is _______ and _______ respectivelya)...
The correct isotope used to remove brain tumors and treat cancer is Co-60 (Cobalt-60).
Co-60 is a radioactive isotope of cobalt that emits gamma rays, which are high-energy radiation. This property of Co-60 makes it useful in medical applications for the treatment of cancer. Here's an explanation of why Co-60 is the correct answer:
1. Radioactive Isotopes in Medicine:
- Radioactive isotopes have unstable nuclei and emit radiation in the form of alpha, beta, or gamma particles.
- These isotopes are used in medicine for various purposes, including diagnosis, treatment, and imaging.
- They can target specific tissues or cells and deliver radiation to destroy cancer cells or abnormal tissue.
2. Treatment of Cancer:
- Gamma radiation emitted by Co-60 can be used to treat cancer.
- The high-energy gamma rays can penetrate deep into the body and damage the DNA of cancer cells, inhibiting their ability to divide and grow.
- Co-60 is commonly used in radiation therapy, where it is delivered externally to the patient's body using machines called linear accelerators.
- The radiation is precisely targeted to the tumor, minimizing damage to surrounding healthy tissues.
3. Advantages of Co-60:
- Co-60 has a long half-life of about 5.27 years, which means it remains radioactive for a relatively long time.
- This property is advantageous in medical applications as it allows for a continuous supply of radiation for treatment purposes.
- Co-60 is also relatively easy to handle and transport, making it widely available for medical use.
4. Other Isotopes Mentioned:
- U-235 (Uranium-235) is primarily used in nuclear reactors for power generation, rather than medical purposes.
- Na-24 (Sodium-24) is used in medical imaging and as a tracer for studying bodily functions, but it is not commonly used for cancer treatment.
- Iodine isotopes, such as I-131, are used to treat certain types of thyroid cancer, but they are not specifically used to remove brain tumors.
In conclusion, Co-60 is the correct isotope used to remove brain tumors and treat cancer. Its gamma radiation can effectively target and destroy cancer cells, making it an essential tool in radiation therapy.
