| What controls the penetrating power of the xray beam? | Kv |
| What is the maximum permissable dose per year | 50 mSv |
| What will reduce scatter radiation? | Collimating the Light beam diaphragm (LBD) |
| what is the focal spot? | The area on the target which is bombarded with electrons |
| smaller focal spot would be used for | a small area/small animal (hamster) |
| larger focal spot would be used for | a larger area/larger animal (lion) |
| what happens when the focal spot is increased (larger focal spot) | more penumbra, blurry image, not as focused, covers larger area |
| what happens when focal spot is decreased (small focal spot) | less penumbra, clearer image, more focused, covers smaller area |
| what is the focal spot usually angled to? | 22 |
| RPA | doesn't work in practice, advises RPS on queries, sets out local rules |
| what must be put up inside xray room for easy viewing | the local rules |
| what is known to be a safe area to stand away from patient being xrayed | 2 metres |
| RPS | works at practice, in charge of day to day upkeep involvement in the xray room and safety regarding radiation |
| the kV controls... | the speed of the electrons and therefore the PENETRATING power of the xray beam |
| the mA controls... | the AMOUNT of xrays produced |
| If the mAs is halved, what should be done to the Kv to compensate? | kV should be increased by 10 |
| if the mAs is doubled, what should be done to the kV to compensate? | the kV should be decreased by 10 |
| motor neurons | transmit nervous impulses away from CNS |
| Sensory neurons | transmit nervous impulses TOWARDS the CNS |
