Abstract
A radiation shield in the form of a stranded curtain made up of bead-chains whose material and geometry are selected to produce a cross-sectional density that is the equivalent of 0.25 mm or more of lead and which curtain may be mounted on various radiological devices to shield against scattered radiation while offering a minimum of obstruction to the radiologist.
Claims12
A method of constructing a radiation shield comprising the steps of:
- assembling a plurality of radiation-shielding elements;
- connecting said elements in sets to form a plurality of elongated strings of said elements;
- disposing the upper ends of said strings adjacent to each other to form a stranded curtain;
- and
- selecting the material and geometry of said elements such that said curtain has a cross-section density which is the equivalent of a predetermined thickness of lead.
2 more elements
A radiation shield comprising:
- a plurality of flexible strings of radiation-shielding material;
- and
- means for holding the upper ends of said strings adjacent to each other to form a flexible stranded curtain having a cross-sectional density which is the equivalent of at least 0.25 mm of lead.
