Abstract: A two-piece radiation shield garment for the human body is disclosed comprising an adjustably overlapping vest to protect the upper body and a wraparound skirt to protect the lower body. The vest and skirt are constructed of multiple inner layers of flexible radiation shielding material covered with nonshielding fabric or other material. The vest and skirt may be attractively fashioned and decorated to encourage their use as a shield garment for women. The vest includes a rear shield panel joined to a pair of overlapping front shield panels. Similarly, the skirt includes a rear shield panel connected to a pair of overlapping front shield panels. The overlapping front panels of the vest and skirt have wide cooperating horizontal bands of Velcro-type tape closures providing an adjustable fit and a secure closure for the heavy materials. The vest and skirt overlap in the waist region when worn to provide continuous vertical and all-around protection to the body while allowing freedom of movement to the wearer.
