New techniques are proposed for the handling and fabrication               of scintillating crystal radiation detectors such as NaI(Tl),                   which is highly valued because of its exceptionally good energy                 resolution.  This crystal, as well as others used for radiation                 detection, is extremely fragile and hygroscopic.  It is grown,                  cleaved, and packaged in a dry atmosphere.  The new techniques                  proposed include the use of water free, liquid bathes for                       cleaning and handling, and optical gels for packaging and                       mechanical shock isolation.  In addition, it is proposed to                     fabricate larger detectors from irregularly shaped by-product                   crystals. The possible benefits of the proposed work are: (1)                   less expensive detectors for radiation measurements; (2) easier                 to handle detectors; and (3) larger detectors than previously                   available for high energy photon measurements.
