Orphan date September 2008 A Lewis Lead also called the S5 lead is a modified EKG lead used to detect atrial flutter waves when atrial flutter is suspected clinically but not definitely demonstrated on the standard 12 lead EKG. In order to create the Lewis Lead, the right arm electrode is moved to the right, second intercostal space adjacent to the Human sternum sternum . Then the left arm electrode is moved to the right, fourth intercostal space adjacent to the sternum. The Lewis Lead is then read as Lead I on the EKG and, since in most patients it will be roughly perpendicular to the wave of atrial depolarization , flutter waves may be more apparent.

File Lead shielding.jpg thumb Lead bricks are commonly used as radiation shielding. Lead shielding refers to the use of lead as a form of radiation protection to radiation shield shield people or objects from radiation . Lead can effectively attenuate certain kinds of radiation because of its high density and high atomic number principally, it is effective at stopping alpha ray s, gamma ray s, and x ray s. Lead s high density is caused by the combination of its high atomic mass and the relatively small size of its bond lengths and atomic radius. The high atomic mass means that more electron s are needed to maintain a neutral charge and the small bond length and a small atomic radius means that many atoms can be packed into a particular lead structure. Because of lead s density and large number of electrons, it is well suited to scattering x rays and gamma rays. These rays form photon s, a type of boson , which impart energy onto electrons when they come into contact. Without a lead shield ... .
