background: technetium-99m radioisotope is the backbone of any nuclear medicine institute. this radioisotope is acquired by the elution of molybdenum-99/technetium-99m generator which emits 141 kev gamma ray and having 6.04 hour half-life. occasionally the contents of molybdenum-99 may mix up with elute, which may affect image quality and patients may receive higher doses than recommended. this...

Background and purpose: 99mTc is a widely used radionuclide in nuclear medicine and research nowadays. Two types of 99 Mo/99mTc generators were studied in 2013 and 2014 to test the quality of the eluates. In this study we measured the radionuclide purity for possible 99Mo breakthrough, the radiochemical purity, the pH, and the aluminum content of eluates. Materials and methods: Two type genera...

In this research, a new technetium-99m generator has been developed with addition of Cerium oxide to alumina column.  The adsorption behaviors of 99Mo in the form of molybdate and 99mTc in the form of pertechnetate on CeO2/Al2O3 was investigated and showed that the adsorption capacity of molybdate on this generator is higher than usual generator using Al2O3. Ceric ions were selected as an addit...

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...

Technetium is an element that is artificially produced and all its isotopes are radioactive. Several investigations have been performed on the subject of the production of Tc radioisotopes using cyclotrons. Among these radioisotopes, 99mTc with a half-life of 6.02 h and gamma-ray spectrum with an energy peak at 140.5 keV has a vast application in nuclear medicine. More than 85% of administered ...
