What is the expected penetrating power in steel for X-rays ranging from 50 kV to 150 kV?

The expected penetrating power of X-rays for voltages ranging from 50 kV to 150 kV typically falls within the range of 1/8 inch to 3/4 inch in steel. This outcome is due to the relationship between the energy of the X-rays, measured in kilovolts (kV), and their ability to penetrate materials. As the energy increases, as seen in X-ray tubes operating at higher kilovolts, the X-rays have greater penetrating capabilities.

At lower energies, such as 50 kV, the X-rays can penetrate a minimal amount of steel, likely around 1/8 inch. As the energy increases toward 150 kV, the penetrating ability also increases, moving closer to the upper range of 3/4 inch. Thus, the range chosen reflects the realistic penetrating capabilities of diagnostic X-rays as they interact with steel, aligning with established industry standards and empirical data related to X-ray penetration characteristics.

Considering this information, the option stating a range of 1/8 inch to 3/4 inch for X-rays between 50 kV and 150 kV accurately captures the expected performance within this energy threshold. Additionally, the other ranges provided do not align with known penetration capabilities
