NUCLEAR MEDICINE-RADIOACTIVITY-LESSON 136
Radioactivity:
The giving out of power or energy in the outward appearance of elements or beams originating from the center of a matter is called radioactivity.
Radionuclides:
A radionuclide is a material that imparts elevated power particles or beams seeing that it falls to pieces. Radionuclides are created in what's more a nuclear reactor or an electrically exciting substance to gather speed. Not later than glow with established particles bring about commotion and wavering.
Half-life period:
Half-life is the point in time or occasion necessary intended for electrically excited substances that are radionuclides to go down partial that is half of its radioactivity by breakdown.
Why Radionuclides are Important in Medicine Field?
1. The information of the half-life of a radionuclide is of great consequence to be decisive how far the radioactive material will send out radioactive material will give off radioactivity in a patient's body.
2. The half-life is obliged to designate extensive adequate amount to make available for an investigative illustrations at the same time to curtail patient contact to radiation of the patient. For instance the half-life period of technetium 99 m (99m Tc) is about six hours is a perfect radionuclide used in investigative illustrations through imaging technique in medicine.
3. Radionuclides give out three kinds of radioactive particles such as alpha, beta particles, and gamma. In all the three gamma rays have the greatest break through power comparing with alpha rays and beta rays. Gamma rays are further having ionizing power and convenient to physicians together in the diagnosis and the management a disease.
The next lesson will describe about nuclear medicine tests. Okay.
