Abstract The Mo adsorption/99mTc elution properties of alumina used as Mo adsorbents are examined for the development of 99Mo/99mTc generators using 99Mo produced by the (n, γ) method. MoO3 is irradiated by the Kyoto University Research Reactor (KUR). The alumina columns are filled with three types of alumina made from different raw materials. In this paper, elongated tubes are used as columns and the properties under Mo dynamic adsorption conditions on alumina are compared with those under static adsorption conditions. The results obtained suggest that the 99Mo/99mTc ratio specified by the Minimum Requirements for Radiopharmaceuticals of Japan (MRRP) is greatly affected by the method of adsorbing Mo on alumina.

The book deals with many factors, including anti-nutritional, determining the biological value of feed components. Considerable attention is paid to the minimum requirements that must be imposed on the quality of raw materials and can be met in each economy. Provides information on poisonous plants and weeds that may be present in the plant material and cause phytotoxicity. The causes of diseases of feed nature associated with metabolic disorders, and ways to prevent them. The consequences of technological violations in poultry farming are revealed. The role of the quality of raw materials, biologically active and mineral substances in the prevention of certain diseases of forage nature, increasing the productivity of poultry, reducing the cost of feed and their production costs. It is addressed to specialists and managers of poultry farms, feed industry enterprises, researchers, postgraduates and students.
