Do a google search and find out at least one way radioactiveisotopes are used in a medical setting to diagnose or treat adisease in a patient. Write the details about that radioactiveisotope and how does it work. What is the half life of thisradioactive isotope? Cite the references.
Answer:
Radioactive isotopes can be used to diagnose or treat anabnormal condition in a person.Radiation therapy by gamma rays has been extensively used to killcancer cells.Radioisotopes are also used to sterilize surgical instruments.
Mechanism of function:1. They emit tractable radiation which helps them to use asprobes.2. High energy radiation emitted by nuclides can be used to killharmful cancerous cells.
Techniques based on radioisotopes:1. X-ray2. CT scan3. PET scan
The half-life of radio-isotopes used in medicine:1. Tc-99 = 6 hrsIt is used to image heart muscle, lungs, liver, and brain
2. Mb-99 = 66 hrsIt produces Tc-99
3. Co-60 = 5.26 yrsUsed in cancer therapy
4. I-131 = 8.02 daysUsed in thyroid therapy
