Question: 1 / 400

If a radiograph is taken at a voltage of 500 kV and the voltage is increased, what is likely to occur?

Significant increase in film granularity

No significant change in granularity

When a radiograph is taken at a high voltage, such as 500 kV, increasing the voltage further typically results in minimal to no significant change in granularity. Granularity refers to the degree of visible grain on the radiographic film, which is impacted by factors such as exposure time, radiation dose, and the type of film used rather than the operating voltage alone.

Higher voltages generally produce higher energy X-rays, which penetrate the material more effectively and can improve image clarity and definition. The film's inherent characteristics heavily influence granularity; thus, increasing the voltage may enhance exposure without notably affecting the film grain structure. Therefore, selecting an option indicating no significant change in granularity aligns with understanding the interaction between voltage and film characteristics in radiographic testing.
