background: 99mtc is a widely used radioisotope in nuclear medicine centers which is obtained by elution from mo-99/tc-99m generators. usually the generators are either supplied by the iran atomic energy agency or by private companies from foreign countries. in this study we have measured 99mo contamination in 99mtc elute from different generators in a period of one year. materials and methods:...

Tera Becquerel quantities of a number of radioisotopes such as 131I, 99Mo, 32P, 153Sm, 51Cr, 82Br, 203Hg, 140La, 46Sc, etc. are produced in various radiochemical forms and regularly supplied through Board of Radiation & Isotope Technology (BRIT) for applications in medicine, industry, biology, agriculture and research & development activities. These radioisotopes are produced by neutron activat...
