What is the lead thickness requirement for equipment operating between 100 and 150 kVp?

The lead thickness requirement for equipment operating between 100 and 150 kVp is indeed 0.35 mm. This specification is based on the need for adequate radiation shielding to protect personnel and the public from unnecessary exposure to scatter radiation during medical procedures.

In this energy range, 0.35 mm of lead is determined to provide sufficient attenuation of the X-ray beam to achieve a balance between safety and the need for diagnostic imaging quality. This standard is derived from guidelines established by regulatory bodies and ensures that the equipment is adequately shielded based on its operating voltage.

Choosing a lead thickness that is too low would compromise safety by allowing more radiation exposure than acceptable, while choosing a thickness that is unnecessarily high could lead to increased costs and potential issues with equipment performance and weight. Hence, the specification of 0.35 mm aligns with the requirements set forth for efficient radiation protection at these kilovolt peaks (kVp).
