Nuclear Medicine looks at...
Anatomy and Physiology
3 common types of Radiation
1. Alpha- slow moving, cannot menetrate skin.
2. Beta- faster moving, can penetrate 2cm radius of tissue.
3. Gamma- high speed, high energy, greatest penetrating power.
Alpha Radiation
- large particle
- doesn't penetrate matter very well
- leaves all of its energy in a small radius
-No predominant use in Nuclear Medicine
Beta Radiation
Limited ability to penetrate tissue
- good for therapy, bad for imaging
- Iodine-131
- Strontium-89 (met bone pain)
- Phosphorous-32 (pleural effusions)
Gamma Radiaiton
Small bundle of energy - Photon
Penetrates tissue very well
passes through tissue and deposits minimal energy.
- excellent for imaging, poor for therapy
- Technetium-99m
- Thallium-201
How is gamma radiation formed?
Positrom particle collides with an electron resulting in the release of two gamma photons.
Unit of measurement for radiopharmaceuticals.
