An experimental investigation was made to determine the limiting radiation field parameters in the use of the partial shieid concept in ground support applications for nuclear aircraft. When used in the presence of multiple sources of radioactivity, such as an activated airplane, the partial shield can reduce the radiation exposure of a mechanic to that amount which originates in his immediate work area, by providing shielding on aii sides except for an opening through which work is performed. Another feature of the partiai shield concept is that it utilizes the higher total radiation dose which the hands are permitted to receive over the allowed total body tolerance. A reactor fuel element was used as a source to investigate the radiation protection characteristics of two elementary versions of the partial shield concept. One is the open-front type, which is simply a shield box with a work opening. The other is the body-shielded, open-front type. This type is simiiar to the open front version except that it has an additional body shield inside the box. Field conditions are defined in which direct maintenance would be possible on a nuclear airplane by use of these types of partial shields. (auth)
