Which material is commonly used for temporary shielding during x-ray procedures?

The use of lead sheets for temporary shielding during x-ray procedures is primarily due to lead's high atomic number and density, which effectively attenuate x-ray radiation. Lead is highly effective at stopping or reducing the intensity of x-rays, making it an ideal choice for protecting personnel and patients from unnecessary radiation exposure during imaging procedures. Additionally, lead sheets can be easily handled and positioned as necessary, allowing for flexible shielding that can be adapted to various clinical setups.

While other materials like aluminum do provide some level of radiation protection, they are not as effective as lead in terms of shielding against x-rays. Cardboard and plastic barriers do not have the necessary density or atomic structure to significantly reduce x-ray transmission, making them inadequate for effective radiation protection in a clinical environment.
