A lightweight, breathable material which has radiopaque qualities and a method for making the radiopaque material. In a preferred embodiment, a lightweight fabric, such as a cloth surgical mask liner ( ) or an entire surgical mask ( ), is impregnated with a lightweight radiopaque compound, such as a barium sulfate compound, to impart radiopaque qualities. Impregnation of the lightweight radiopaque compound can be performed in any number of ways, including soaking the fabric in a solution containing the lightweight radiopaque compound, using the fabric as a filter in a passing solution of the lightweight radiopaque compound, placing the fabric in a reaction chamber between reagent solutions whose interaction will form the lightweight radiopaque compound and impregnating the fabric with one reagent and then exposing it to a complementary reagent whose reaction with the first reagent will form a lightweight radiopaque compound. To enhance the efficiency of impregnation, an additive, such as a Gum Arabic or Guar Gum adhesive, can be added to the solution containing lightweight radiopaque compound or to the fabric itself. While a surgical mask is provided as one example, the principles of the invention can also be applied to a broad range of other items including surgical hoods, hospital gowns, gloves, partitions, patient drapes, coverings etc.

An article which has radiopaque qualities and a method for making it. In a preferred embodiment, a lightweight fabric, such as a cloth surgical mask liner ( ) or an entire surgical mask ( ), is impregnated with a relatively lightweight radiopaque material, such as a barium sulfate compound, to impart radiopaque qualities. In other embodiments, a similar fabric is used to produce an entire radiation protective jumpsuit, a tent, wallpaper or a liner for a commercial aircraft cabin. Impregnation of the relatively lightweight radiopaque material can be performed in a number of ways, including soaking the fabric in a solution containing the relatively lightweight radiopaque material or using the fabric as a filter in a passing solution of the lightweight radiopaque material. In one preferred embodiment, which is particularly suited for mass production of relatively lightweight radiopaque fabrics, a lightweight radiopaque material is mixed with a liquid polymer. The polymeric mixture is then laminated onto one or more layers of the fabric and perforated, as needed, to produce a plasticized form of lightweight radiopaque fabric.

Articles, including fabrics and film layers, are disclosed which can protect against multiple hazards, including radiation, chemical, biological agents, metal projectiles and fire hazards. In some embodiments, the fabrics and films of the present invention are used to produce garments having protection against multiple hazards and superior heat dissipating properties. A radiation protective compound is preferably created by mixing a radiopaque material, such as barium, bismuth, tungsten or their compounds, with powdered polymer, pelletized polymer or a liquid solution, emulsion or suspension of a polymer in solvent or water. This radiation protective mixture can then be laminated or otherwise adhered to other types of protective films or fabric, such as the protective polymer films or fabrics used for chemical protective garments, biological protective garments, bullet proof vests or fire retardant garments. The principles of this invention can also be applied to a broad range of other articles including surgical hoods, hospital gowns, gloves, patient drapes, partitions, coverings, jumpsuits, ponchos, uniforms, fatigues, tents, probes, envelopes, pouches, wallpaper, liners, drywall, house sidings, house foundations, house roofings etc.

Compositions and processes for forming radiopaque polymeric articles are disclosed. In one embodiment, radiation inspection apparatuses and methods are then used to determine the presence and attributes of such radiopaque polymeric articles. A radiopaque polymeric article of the present invention can be created by mixing a radiopaque material, such as barium, bismuth, tungsten or their compounds, with a powdered polymer, pelletized polymer or liquid solution, emulsion or suspension of a polymer in solvent or water. In addition to creating radiation detectable objects, the radiopaque polymeric materials of the present invention can be used to create radiation protective articles, such as radiation protective garments and bomb containment vessels. Enhanced radiation protection can also be achieved through the use of nano-materials. The principals of the present invention can be used to provide protection against other types of hazards, including fire, chemical, biological and projectile hazards.

The present invention provides a breathable, lightweight material which has radiopaque qualities and is easy to produce. In the preferred embodiment, a lightweight fabric, such as a surgical mask liner or an entire surgical gown, is formed by mixing a lightweight radiopaque compound, such as barium sulfate, with a polymer filler, preferably polyethylene, to impart radiopaque qualities to the mixture, then extruding the mixture into a plurality of filaments to form a porous, nonwoven fabric mass, and forming the filament mass into a web suitable to be used as a garment liner or ply in a multi-ply fabric.

High Intensity Repetitious Training (HIRT) is an exercise regimen consisting of approximately three minutes of intense exercise that puts an exerciser at the end of the anaerobic energy transfer system and prevents the exerciser from entering the aerobic energy transfer system. The HIRT Program exercise regimen subjects the muscles to high frequency intense muscle contractions for approximately three minutes to the point that the lactic system reaches a maximum followed by a period of rest for at least one to two minutes to restore creatinine and remove some of the lactate acid out of the blood stream. The HIRT exercise regimen enhances the benefits of lactate accumulation, post-exercise insulin and growth hormone release with lipolysis or fat reduction.
