Expert Solution

Radioactive isotopes can be used to diagnose or treat an abnormal condition in a person.
Radiation therapy by gamma rays has been extensively used to kill cancer cells.
Radioisotopes are also used to sterilize surgical instruments.

Mechanism of function:
1. They emit tractable radiation which helps them to use as probes.
2. High energy radiation emitted by nuclides can be used to kill harmful cancerous cells.

Techniques based on radioisotopes:
1. X-ray
2. CT scan
3. PET scan

The half-life of radio-isotopes used in medicine:
1. Tc-99 = 6 hrs
It is used to image heart muscle, lungs, liver, and brain

2. Mb-99 = 66 hrs
It produces Tc-99

3. Co-60 = 5.26 yrs
Used in cancer therapy

4. I-131 = 8.02 days
Used in thyroid therapy

Many radioactive isotopes are used in medicine for imaging and treatment purposes. The specific isotopes used depends on the particular organ or body system being studied (for example, Xe-133 is used to image lung function and blood flow.) For thyroid imaging, isotopes of iodine are used, commonly I-123 and I-131, which have half-lives of 13.2 hours and 8.0 days, respectively. Why is iodine used for thyroid imaging (as opposed to any other element)? I-129 is an extremely rare isotope of...

The element technetium (atomic number 43) is radioactive and one of its isotopes, 99Tc, is used in medicine for diagnostic imaging. The isotope is usually obtained in the form of the pertechnetate anion, TcO4-, but its use sometimes requires the technetium to be in a lower oxidation state. Reduction can be carried out using Sn2+ in an acidic solution. The skeleton equation is TcO4- + Sn2+ → Tc4+ + Sn4+ (acidic solution) Balance the equation by the ion–electron method.

Exercise 27.20 Cyclotrons are widely used in nuclear medicine for producing short-lived radioactive isotopes. These cyclotrons typically accelerate H− (the hydride ion, which has one proton and two electrons) to an energy of 5MeV to 20MeV. This ion has a mass very close to that of a proton because the electron mass is negligible−about 1/2000 of the protons mass. A typical magnetic field in such cyclotrons is 1.7 T . Part A What is the speed of a 5.0-MeV H−?...
