How do radioactive elements are utilized in diagnosis treatment of diseases the rest involve in the method of protection?

Answer 1

1. All organs in the body act differently chemically due to the presence of specific chemicals absorbed by the organ. This knowledge has helped develop diagnostic radiopharmaceuticals, to help examine the blood flow to the brain, functioning of the heart, lungs, liver functions, kidneys, excess growth of bones, etc. it also helps in predicting the effects of surgery and assess changes since the start of treatment. This non-invasive technology helps in observing the organ functions and diagnosing abnormalities without the patient experiencing any form of discomfort. The most widely used radioactive isotope is technetium-99m, that has the ability to disappear without a trace after completion of the test, in a short time. Thallium-201 chloride or technetium-99, is used in Myocardial Perfusion Imaging for detection and prognosis of coronary artery diseases.

Answer 2

Radioactive elements are utilized in the diagnosis and treatment of diseases by having the patient ingest a radioactive dye, or an injection is given, and then an x-ray or scan is taken to see the organs involved. In the case of using radio activity to treat a disease, the patient is given an x-ray that is more powerful than a normal x-ray, targeted to a certain part of the body, to kill the disease.

Answer 3

Radioactive elements are used in imaging techniques like PET scans to diagnose diseases by detecting abnormalities in the body. In cancer treatment, radiation therapy uses targeted radioactive elements to kill cancer cells. Protection involves shielding, time management, and distance from the radiation source to minimize exposure and ensure safety for both patients and healthcare providers.
