Abstract
A dosimeter device that is fabricated from a flat member separated into panels along fold lines. In an illustrated embodiment, a first panel has two attenuators thereon, a first attenuator formed of a first material and a second attenuator formed of a second material. The first panel also has a window or opening formed thereon. A second panel also has two attenuators thereon, a third attenuator formed of the same material as the first attenuator on the first panel and a fourth attenuator formed of the same material as the second attenuator on the first panel. The second panel is separated from the first panel by a fold line, and the second panel also has a window or opening formed thereon. A third panel is separated from the second panel by a second fold line, and has a radiation sensitive member thereon. When the flat member is folded along the fold lines, the third panel becomes sandwiched between the first and second panels, and the first and third attenuators oppose each other with the radiation sensitive member sandwiched therebetween. Likewise, the second and fourth attenuators oppose each other with the radiation sensitive member sandwiched therebetween. Additionally, the windows on the first and second panels oppose each other with the radiation member sandwiched therebetween. Preferably, indicia is provided on at least the third panel to provide certain information.
