Studies on the adsorption of ~(125)I on metallic pellets for their potential applications in bone densitometry for the diagnosis of osteoporosis

摘要

~(125)I - bone densitometry sources find extensive application in the diagnosis of osteoporosis by using single photon absorption (SPA) technique. Silver pellets of size approx 2.5 mm (f) x 0,6 mm (I) were developed as base matrix for adsorption of ~(125)I Determination of specific surface area and pore size analysis of plain silver and palladium coated silver pellets was carried out. Experimental conditions for quantitative adsorption of ~(125)I were optimized and the sources containing upto ~ 1 48 GBq of ~(125)I were prepared The teachability of sources was found to be < 0 01 percent Such ~(125)I - bone densitometry sources developed at our end have potential of application in the diagnosis of osteoporosis after encapsulation of sources within titanium capsules.
