A launderable lead blanket cover system for rehabilitating contaminated lead blankets and which provides a lead blanket launderable cover. Lead blankets which can be removed from a nuclear facility or which are manufactured directly, include an outer cover which is heat sealed around the periphery to the inner lead blanket. The heat sealed periphery can include a plurality of blanket supporting metal grommets having a uniform predetermined spacing. A contaminated lead blanket which cannot be removed from a nuclear facility, has the contaminated cover removed in the nuclear facility and securing strips are secured to the inner cover. The contaminated lead blanket then is rehabilitated by adding a replaceable cover open on one end and having a heat sealed periphery and metal grommets in the other three sides. The open end with the lead blanket inside is then folded over and sealed, such as with an adhesive and then metal grommets can be secured through the sealed periphery to complete the lead blanket. A replaceable cover lead blanket can also be initially formed, if desired. Utilized with either type of lead blanket embodiment is a launderable and incinerable outer cover. The launderable cover includes two piece securing grommets having the same spacing as the metal grommets. The pieces are snapped together through the metal grommets to secure the launderable cover to the lead blanket and unsnapped to remove the cover for laundering or incineration.
