The incorporation of glucosamine-'4C by Ehrlich ascites tumor cells has been mess ured both in vivo and in vitro. A considerable amount of high molecular weight radio active material appears outside of the cells under both conditions. The radioactive extracellular fluids were subjected to gel ifitration and to chromatography on DEAE cellulose (diethylaminoethyl cellulose) columns. These experim...

background: radiation shielding properties is an important for a material wish can be used the photon attenuation coefficients of clay produced using different rate of boron have been measured for the purpose of radioactive waste disposal. materials and methods: the measurement has been performed using gamma spectrometer contains nai (tl) detector at the photon energies of 662, 1173 and 1332 ke...

Background: The Ural region is highlighted among other Russian regions for its unfavorable radiation situation and complexity of the overall environmental situation. The source of man-made radioactive contamination is the work of the "Mayak" Production Association. A significant radioactive contamination has happened as a result of several radiation incidents in the early period ...

This paper reports the results of a study performed for the Oregon Department of Energy. The objectives of the study were to characterize the range of radioactive material shipments through the state and to determine the worst radiological hazards which might arise if these shipments were involved in transportation accidents. The direct and indirect radiological hazards were analyzed for worst ...
