NPO is the leading manufacturer of lead wool blankets in the world, made in Illinois since 1976.

Lead wool blankets are the industry standard radiation shield product for industrial applications.  They are typically used to create a barrier between a radiological source and the rad worker.  Lead blankets are often hung on scaffold or cables by S-hooks to create a shield wall.  They may also be draped over pipes / valves / heat exchangers or placed on the floor to shield sources from below.

Lead wool blankets are created by forming continuous lead wool rope into the desired shape by use of rollers and dies.  The form is then sewn, quilted, and cross stitched inside a layer of PVC to create a billet.  The billet is RF sealed inside a second layer of PVC, creating waterproof barrier.  The excess PVC is trimmed and grommets are installed.

Lead wool blankets are cost effective, durable, and versatile.
