The intravenous administration of emulsified fat in concentrations suitable for nutritional purposes is not applicable for clinical use because an emulsion stabilizer free of undesirable effects has not yet been developed. Pending the availability of a satisfactory stabilizer, the possibility of parenteral administration of fat by other routes deserves further exploration. Data reported on the ...

Accidental or intentional release of radioactive materials into the living or working environment may cause radioactive contamination. In nuclear medicine departments, radioactive contamination is usually due to radionuclides which emit high energy gamma photons and particles. These radionuclides have a broad range of energies and penetration capabilities. Rapid detection of radioactive contami...

effect of scale on the hydrodynamics of gas-solid fluidized beds was investigated in two fluidized beds of 152 mm and 78 mm in diameter.  air at room temperature was used as the fluidizing gas in the bed of sand particles. the radioactive particle tracking (rpt) technique was employed to obtain the instantaneous positions of the particles at every 20 ms of the experiments. these data were used ...

background: radon (222rn) measurement in the residential environments is very important because of its effecting on human health and causing cancer in the respiratory system. 222rn is individually responsible for half of the natural radiation received in humans and influences on human by breathing. hence, this study was undertaken to access the 222rn level in the dormitories of kerman universit...

introduction: skin dose and depth dose distribution of some beta sources that can contaminate skin or protective clothing covering the skin have been calculated using varskin2. materials and methods: in this research, absorbed dose to skin and depth dose from the skin surface have been calculated for 90sr/90y, 147pm, 32p beta emitter radioisotopes by using input parameters: activity of source, ...

The biosynthesis of ubiquinone-8 from radioactive mevalonate by cultures of Tetrahymena pyriformis is demonstrated. Under normal conditions the incorporation of this radioactive precursor into ubiquinone and the triterpenoid alcohol tetrahymanol reflects the amounts of these two compounds in the cell. Growth of T. pyriformis in the presence of cholesterol results in a complete inhibition of inc...

In this bachelor thesis, which is a part of the project RadioRoSo, we examine and analyze waste from Magnox power plants. These power plants were mostly situated in the Great Britain and they were operated between 1956 and 2015. The analyzed waste mainly consists of pieces of Magnox alloy AL80. Springs from alloy Nimonic 80A are also present in the waste and they are considered to be highly rad...
