Positron emission tomography (PET) are widely accepted and used as an effective medical imaging method. We have studied on the dual radioisotopes C11 Cu60 together by modifying isotopes in Standard cyclindirial PET through GATE simulation. scan proper resolution intervals distances between sources present differences parameters such full width at half maximum (FWHM), intensity contrast. Applyin...
Five mesa p+-i-n+ photodiodes (each of 0.126 mm2 area) were investigated as conversion devices for X-ray-voltaics, in order to understand the comparative effects between different semiconductor materials, device structures, and X-ray incident power, explore them use future radioisotope microbatteries. Three materials (AlInP, InGaP, GaAs) three i layer thicknesses one material, AlInP (2 ?m, 6 10...
This paper presents the results of TL and OSL dating of soil and fragments of bricks from a grave, which was occupied by two mummified nuns, found at "Luz" Monastery, located in the state of São Paulo, Brazil. The TL and OSL ages were compared to C-14 dating ones obtained from bone collagens of the mummies. The majority of the ages is related to the eighteenth century. The gamma-ray spectroscop...
Purpose: To evaluate the suitability of Tc-DTPA as a radiotracer in Persian cat's renal scintigraphy. Methods: twelve adult healthy Persian cats were selected. For scintigraphy, the animals were anesthetized and TC-DTPA was injected via the femoral vein as a bolus at a dose of 1.5 mCi. Immediately after intravenous injection of radiotracer, scintigraphic operation was conducted on the renal org...
