An advanced relativistic approach is presented to studying spectroscopy and photodynamics of the exotic (pionic) atomic systems based on Klein-Gordon-Fock equation many-body perturbation theory with accounting for fundamental electromagnetic strong pion-nuclear interactions. The interactions are taken into account by means using generalized optical potential model effective Ericson-Ericson pote...
Radioactive materials used in nuclear medicine are the radioisotopes or drugs that are identified with radioisotopes. A radiopharmaceutical transfusion is one of diagnostic methods and a radiation value approved should be measured. The nuclear medicine images of diagnostic methods can be made by a gamma camera (γ-camera). In this article, we used MCNPX2.4 for internal dosimetry assessment when ...
We show that optical excitation of radical triplet pair systems can produce a fourfold NMR signal enhancement in solution, without the need for microwave pumping. Development of optical hyperpolarization methods will significantly impact all NMR user groups by boosting sensitivity and reducing signal averaging times.
The method of electron paramagnetic resonance (EPR) spectroscopy for tooth enamel is applied to individual radiation dose determination to residents of two villages (Dolon and Mostik) in the vicinity of the Semipalatinsk nuclear test site in Kazakhstan. These villages are located near the central axis of the radioactive fallout trace of the most contaminating surface nuclear test conducted in 1...
some new water-soluble schiff base complexes of na2[m(5-so3-1,2-salophen)].nh2o; (5-so3-1,2-salophen = n,n’-bis(5-sulphosalicyliden)-1,2-phenylendiamine); na2[m(5-so3-2,3-salpyr)(h2o)n].2h2o; (5-so3-2,3-salpyr = n,n’-bis(5-sulphosalicyliden)-2,3-diaminopyridine); and na2[m(5-so3-3,4-salbenz)(h2o)n].nh2o; (5-so3-3,4-salbenz = n,n’-bis(5-sulphosalicyliden)-3,4-diaminobenzophenon); where m = cu, n...
Background: CT scan and nuclear medicine exams deliver a great part of medical exposures. This study examined professional radiation hazards in CT scan and nuclear medicine workers. Methods : In a cross sectional study 30 occupationally exposed workers and 7 controls (all from personnel of a laboratory) were selected. Physical dosimetry was performed for exposed workers. Blood samples were ...
• Ion-irradiated ThO 2 is not uniform with respect to Raman spectroscopy, thus many points are analyzed assess the damage. profiling of damage depth agrees quite well simulation predictions. Nuclear reactor conditions can be emulated in part by exposing potential fuel materials, such as , ion beam radiation. Changes properties then provide invaluable insight into how material will perform a fue...
