production of some high specific activity radioisotopes

the thesis entitled production of some high specific activity radioisotodescomprises three chapters; introduction, experimental, and results and discussion. 1- introduction, includes brief accounts on nuclear fission reactions, uranium targets, chemistry of uranium and fission products, chemical separation concepts, review of some fission-products separation procedures, and radiochemical processing plants. 2- which includes the experimental work, is divided into three main parts: ( 1 ) preparation and irradiation of the uranium targets, (2 ) chemical processing, including (i) digestion of the irradiated uranium targets, (ii) separation and recovery of radioiodine, (iii) separation and recovery of radioruthenium, (iv) batch separation of Sr, Ba, La, and Ce radionuclides, (v) batch separation of Zr, Nb, Te, and Np radionuclides, (vi) separation and recovery of radiocesium, and (vii) recovery of radiomolybdenum, and (3) quality control investigations of the recovered radioisotopes, including the separation yield, recovery yield, radionuclide purity, radiochemical purity, and/or ph-value. it includes also a list of chemicals and a description of the equipments and apparatuses used in the present work
