Russell Gnau, III - Web page: https://patentgrep.com/patent/US5330142A ## CPC - G01T 1/167: Measuring radioactive content of objects, e.g. contamination (whole body counters G01T1/163) - G01T: MEASUREMENT OF NUCLEAR OR X-RADIATION (radiation analysis of materials, mass spectrometry G01N23/00; tubes for determining the presence, intensity, density or energy of radiation or particles H01J47/00) ## Abstract A mobile support frame for supporting radiation detection equipment used to detect radiation from material passed through the frame including a base structure and at least one support member extending substantially upward from the base with at least one detector mount movably supported along the support member such that the detector mount may be located at a plurality of positions along the support member. A radiation detector probe is operatively mounted on the detector mount. The detector mount is rotatable about an axis perpendicular to the support member such that the radiation detection equipment may be orientated in a plurality of positions about said perpendicular axis to monitor the radioactivity from material passed through the frame. ## Claims ### Claim 1 A mobile support frame for supporting radiation detection equipment used to detect radiation from material passed through said frame, said frame comprising; a base structure including a pair of base members, a pair of support members extending upwardly from said pair of base members and disposed in spaced parallel relationship with respect to one another with a cross member extending therebetween at the upper margins of said support members opposite said base members and at least one detector mount movably supported along said support members such that said detector mount may be located at a plurality of positions along said support members; said detector mount being rotatable about an axis perpendicular to said support members such that the radiation detection equipment may be orientated in a plurality of positions about said perpendicular axis to monitor the radioactivity from material passed through said frame. ### Claim 2 A mobile support frame for supporting radiation detection equipment used to detect radiation from material passed through said frame, said frame comprising; a base structure including a pair of base members, a pair of support members extending upwardly from said pair of base members and disposed in spaced parallel relationship with respect to one another with a cross member extending therebetween at the upper margins of said support members and at least one detector mount movably supported along said support members such that said detector mount may be located at a plurality of positions along said support members, a radiation detector probe operatively mounted on said detector mount; said detector mount being rotatable about an axis perpendicular to said support members such that the radiation detection equipment may be oriented in a plurality of positions about said perpendicular axis to monitor the radioactivity from material passed through said frame. ### Claim 3 (depends on 1, 2) A mobile support frame as set forth in either claims 1 or 2 further characterized by said detector mount being rotatable about a second axis parallel to said support member such that the radiation detection equipment may be orientated in a plurality of positions about said second axis to monitor the radioactivity from material passed through said frame. ### Claim 4 (depends on 3) A mobile support frame as set forth in claim 3 further characterized by said detector mount being rotatable about a third axis disposed in spaced parallel relationship with respect to said second axis such that the radiation detector equipment may be oriented in a plurality of positions about said third axis to monitor the radioactivity from material passed through said frame. ### Claim 5 (depends on 4) A mobile support frame as set forth in claim 4 further characterized by including a plurality of detector mounts movably supported along and about said support members and by said support members being telescopically adjustable such that the height of the mobile support frame may be adjusted to accommodate waste as it is passed through said frame. ### Claim 6 (depends on 5) A mobile support frame as set forth in claim 5 further characterized by said cross member being telescopically adjustable such that the distance between said support members may be adjusted. ### Claim 7 (depends on 6) A mobile support frame as set forth in claim 6 further characterized by a pair of castors mounted on each of said base members and adapted for rolling contact with a floor surface such that the support frame may be easily moved. ### Claim 8 (depends on 7) A mobile support frame as set forth in claim 7 further characterized by a control box secured to said cross member for housing radiation monitoring equipment, said control box being sealed on five sides and having a clear cover removably disposed over the open sixth side to allow inspection, but not tampering, of the monitoring equipment. ### Claim 9 (depends on 8) A mobile support frame as set forth in claim 8, said frame further characterized by including a pair of upper detector mounts and a pair of lower detector mounts, radiation detector probes operatively mounted on said upper and lower detector mounts, each of said mounts movably supported along said pair of support members and rotatable about an axis perpendicular to said support members to orientate said probes to detect radiation from material passed through said frame.
