To increase radiation intensity while using an X-ray tube, what should be adjusted?

• A. Tube voltage
• B. Tube current
• C. Exposure time
• D. Filtration level

Answer: (B)

To increase radiation intensity while using an X-ray tube, adjusting the tube current is the best approach. The tube current, typically measured in milliamperes (mA), directly influences the number of electrons produced and subsequently the amount of X-rays generated during radiographic exposure. By increasing the tube current, you enhance the quantity of radiation emitted, resulting in a higher radiation intensity. Increasing the tube voltage also affects the quality and penetrating power of the X-rays, but it does not directly correspond to an increase in intensity as tube current does. Exposure time is another relevant factor, as longer exposures can yield more radiation, but it is a secondary adjustment compared to the more immediate effect of changing tube current. Filtration level, while important for regulating the quality and reducing patient exposure to lower-energy X-rays, does not contribute to an increase in intensity. Therefore, the most effective method for boosting radiation intensity in this context is by adjusting the tube current.
