| traditional unit REM | SI Unit Sievert (Sv) |
| traditional unit Rad | SI Unit Gray (Gy) |
| traditional unit Roentgen (R) | SI Unit C/kg |
| What are the 3 cardinal principles of radiation protection? | 1. Time 2. Distance 3. Shielding |
| What are 4 ways of achieving A.L.A.R.A? | 1. Wear a dosimeter 2. mechanical holding devices 3. close collimation, avoid repeat projections 4. time, distance, shielding |
| At what % of the dose limit must you wear a dosimeter? | 10% |
| TLD | Thermoluminescent Dossimeter |
| OSL | Optically Stimulated Luminescent Dossimeter |

| what's the annual dose limit for EXPOSED WORKERS | 50 mSv (5 rem) |
| what's the dose limit for PREGNANT RAD TECH | 5 mSv (500 mrem) throughout pregnancy or 0.5 mSv (50 mrem) per month |
| what's the dose limit for MINORS | 1 mSv (0.1 rem) per year |
| ALARA | As Low As Reasonably Achievable |
| What's the primary cause for repeat radiographs? | poor communication between the rad tech and the patient |
| What are 2 ways collimation will reduce patient exposure | 1. reduces scatter 2. decreases tissue exposure |
| What are 2 types of specific area shields? | 1. gonadal shielding 2. breast shielding |
| the minimum thickness of a gonadal shield is | 1-mm lead equivalent |
| gonadal shields absorb ___% of the primary beam in the 50-100kV range | 95-99% |
| Where should you stand if this is your fluoroscopic patient's table? | Behind the Radiologist |
