Answer:
The unit typically measured in this context is:
b) R
Explanation:
1. In the context of radiation dose, the unit "R" stands for "roentgen." It is a unit of exposure to ionizing radiation.
2. The roentgen (R) measures the amount of ionization produced by X-rays or gamma rays in a specific volume of air.
3. It is commonly used in the field of radiology and radiation protection to quantify radiation levels and exposures.
4. The other option, "C/Kg," stands for "Coulombs per kilogram" and is a unit of electric charge per unit mass.
5. While the unit C/Kg is used in other areas of physics, it is not typically used to measure radiation exposure or dose.
6. Therefore, in this context, the unit usually measured is "R."
In summary, the correct answer is b) R, which stands for roentgen and is commonly used to measure radiation exposure or dose.
