introduction: scatter radiation is one of the major sources of error in nuclear medicine data processing. different methods of scatter correction have been introduced in order to improve the quality of data. however the best method is to avoid recording of scatter photons in acquisition. the only difference between scattered and non-scattered photons is the energy. pulse height analyzer is the ...
Radioactive copper (II) (diacetyl-bis N4-methylthiosemicarbazone) (Cu-ATSM) isotopes were originally developed for the imaging of hypoxia in tumors. Because the decay of a (64)Cu atom is emitting not only positrons but also Auger electrons, this radionuclide has great potential as a theranostic agent. However, the success of (64)Cu-ATSM internal radiation therapy would depend on the contributio...
background: radiotherapy is the main modality of cancer treatment. there are many chemical radioprotectors which unfortunately have lethal or toxic effect. therefore the search is on to find out natural plant based radioprotectors. a well known medicinal plant,which is more acceptable to the body, tinospora cordifolia, was tested in animal tissues against gamma radiations. radioprotective effec...
abstract background : the application of du emanation for first time contaminated certain areas in the south west region of iraq after the second gulf war (1991). these contaminated areas were discovered in 1994. radioactive contamination was detected using the nuclear enterprise pcm5/1 in soil samples collected from two regions near by grazing lands. this study was done for assessment of du ...
