An eco friendly Apparel that replaces lead with the significantly lighter substance. Lead-free Aprons are the alternative to the traditional Lead (Pb) aprons. The weight difference between a lead-free apron and the traditional lead one is significant. This is because of the other metals like Antimony, Barium or Bismuth which have a smaller atomic weight as lead. When used together, Bismuth and Antimony provide similar qualities to lead. Lead-Free aprons have similar attenuation properties to the traditional lead but can weigh up to 15 - 20% less.
The real advantage in using lead free material is that it is not hazardous to the environment such as lead.
