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.
|
