Final answer:
Patient dose estimation in radiology can be reported as entrance skin exposure (Option 1), bone marrow dose (Option 2), and gonadal dose (Option 3). Thus, the correct options are option 4.
Step-by-step explanation:
When reporting an estimation of patient dose, it can be reported as entrance skin exposure, bone marrow dose, or gonadal dose. In fact, the report can encompass all of these. Entrance skin exposure indicates the dose of radiation absorbed by the skin closest to the source of radiation.
Bone marrow dose is important for evaluating the potential risk of hematological effects since bone marrow is very sensitive to radiation. Gonadal dose is considered when assessing potential genetic impacts due to radiation exposure to the reproductive organs.
The SI unit for radiation dose is the gray (Gy), with 1 Gy equal to 1 joule per kilogram. Radiation doses are calculated by dividing the energy absorbed by the mass of the affected tissue, and it is essential to specify the affected region for accurate dose assessment.
Thus, the correct answer is option 4.
