Iran has taken wide strides in science and technology, particularly in medical and medicinal fields, in recent years.
Iranian President Mahmoud Ahmadinejad unveiled five new home-made radiomedicines in a ceremony in April.
The radiomedicines were developed and produced by Iranian experts at the Atomic Energy Organization of Iran (AEOI) and with the cooperation of the presidential office for science and technology.
Also in April, Iranian Vice-President for Science and Technology Nasrin Soltankhah said, "Five radiomedicines, in whose production the Atomic Energy Organization has played the central role, will be unveiled by the end of Farvardin (mid April)".
She explained that the new radiomedicines are used for "diagnosing and curing refractory diseases, cancer in particular".
In February, AEOI Chief Fereidoun Abbasi announced that Iran is due to unveil 8 new radiomedicines with applications for diagnosis, prevention and treatment of a number of diseases.
"We have produced a number of radiomedicines before, and at present we have 5 new radiomedicines under production," Abbasi said at a ceremony in Tehran at the time.
"They (the new radiomedicines) should pass clinical verifications and then obtain the necessary license from the Health Ministry before they can be unveiled and supplied to the market," he added.
