RAD106 Week 12 Exam
| Term | Definition |
|---|---|
| Time | minimize time |
| Distance | maximize distance |
| Shielding | use shielding |
| Effective dose | the equivalent whole body dose following partial body radiation exposure |
| RED | radiation exposure device |
| RDD | Radiologic dispersal device |
| IND | Improvised nuclear device |
| Coherent scattering | little importance in diagnostic imaging |
| Compton scattering | x-rays throughout the diagnostic rang can undergo an interaction with outer shell electrons that not only scatters the x-ray but reduces its energy and ionizes the atom as well |
| Photoelectric effect | x-rays throughout the diagnostic range can undergo an interaction with inner shell electrons. The x-ray is not scattered, but it is totally absorbed. |
| Attenuation | the product of absorption and scattering |
| Absorption | is an all or none condition for x-ray interaction |
| Barium atomic number | 56 |
| Iodine atomic number | 53 |
| Barium and iodine compounds | used as an aid for imaging internal organs with x-rays |
