Mercuric iodide is a high-density, high-Z semiconducting material useful for gamma ray detection. This makes it convertible to a thermal neutron detector by covering it with a boron-rich material and detecting the 478 keV gamma rays resulting from the /sup 10/B(n,/spl alpha/)/sup 7/Li* reaction. However, the 374 barn thermal capture cross section of /sup nat/Hg, makes the detector itself an attractive absorber, and this has been exploited previously. Since previous work indicates that there are… Expand
