Measured bremsstrahlung photonuclear production of 99Mo (99mTc) with 34 MeV to 1.7 GeV electrons

Nonthermal Flare Emission from Mev-energy Electrons at 17, 34 and 86 Ghz

We present analyses of two solar ares observed with high spatial resolution at 86 GHz with the BIMA millimeter{wavelength telescope and at 17 and 34 GHz with the Nobeyama radioheliograph. The ares were observed on Nov. 24, 1998 and May 1, 1999. At millimeter wavelengths these are impulsive events and therefore they must be produced by MeV energy electrons. The present study using simultaneous o...

Determination of 99Mo contamination in 99mTc elute obtained from 99Mo / 99mTc- generator

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...

Optimization of the rate of production 99Mo-99mTC through fission in the TRR

Technetium is one of the most important radioisotopes recognized in medicine which is obtained through ‎the decay of molybdenum 99.The half-life of this radioisotope is 6 hours and it is capable of 140 kev gamma ray emission. Due to its short half-life, this radioisotope must be produced at the site of consumption, so that the shortest possible time interval between production and consumption c...
