Interpretation: To give advantages of seeding or a sealed tube in treating cancer.
Concept Introduction: Radioisotopes serve some important functions such as analyzing the matter, studying plant growth, and diagnosing medical problems.
Answer to Problem 33LC
The salts of radioisotopes can be sealed in tubes mainly gold tubes and directly inserted into tumors. This method is known as seeding. The radiations such as alpha and beta radiations are emitted by the salts which are useful in killing the cancer cells.
Explanation of Solution
In medicines, the radioisotope function as follows:
- Radioisotopes are used in detecting the disorders in the thyroid gland that is present in the throat. The radioisotope that is used is iodine-131.
- The radioisotope named technetium-99 is used to detect brain tumors as well as liver disorders.
The advantages of seeding are discussed as follows:
Cobalt-60 is used as a radiation source in treating cancer. The radioisotope’s salts can be sealed in gold tubes and then directly inserted into tumors. This method is known as seeding. Alpha and beta radiations are emitted by the salts which are useful in killing the cancer cells.
Thus, the method of seeding is used to treat tumors.
