Rad 201 Final Review
| Question | Answer |
|---|---|
| What is the National Council on Radiation Protection and Measurements (NCRP)? | Reviews regulations formulated by the ICRP and decides ways to include those recommendations in US radiation protection criteria |
| What is the ALARA concept in radiation safety? | A principle for minimizing radiation exposure |
| What is the effective dose limit for radiation workers primarily designed to protect against? | Long term health effects |
| Which agency is responsible for enforcing radiation safety standards in the United States? | Nuclear Regulatory Commission (NRC) |
| What is the purpose of the Code of Standards for Diagnostic X-Ray Equipment established in 1974? | To set safety standards for x-ray equipment |
| What is one of the responsibilities of a Radiation Safety Officer (RSO)? | Monitoring radiation exposure levels |
| What is the primary role of the Radiation Safety Committee (RSC) in a medical facility? | to oversee the radiation safety program |
| What is the primary purpose of diagnostic-type protective tube housing? | To shield against leakage radiation |
| What type of filtration is commonly used to filter the x-ray beam in diagnostic radiology? | aluminum filtration |
| What does automatic exposure control (AEC) do in radiographic imaging? | Maintains consistent image brightness by adjusting exposure time |
| How do radiographic grids affect patient dose? | They increase the required radiation dose to achieve quality images. |
| What is the minimum source-skin distance (SSD) for mobile radiography? | 12 inches (30 cm) |
| What is a critical consideration when performing digital radiography? | Monitoring exposure to avoid overexposure |
| What role do radiographers play during interventional procedures performed by nonradiologist physicians? | they ensure radiation safety and monitor exposure levels |
| How does immobilization help in reducing radiographic exposure? | It prevents motion artifacts and reduces repeat images |
