15 صفحه اولRadon permeability of insulating building materials
The common presence of the radioactive nuclides in the environment cause that the whole population are exposed to radiation. The dose that is annually received by Polish population from natural sources of radiation is about 2.4 mSv per year [1]. According to the UNSCEAR 2000 Report [2], radon is the greatest contributor of exposure to natural radiation for humans. Soil and the rocks on which th...
متن کاملExperimental Investigation of Sinusoidal Tube in Triplex-Tube Heat Exchanger during Charging and Discharging Processes Using Phase Change Materials
In this experiment effect of two full and half width sinusoidal inner tubes in triplex-tube heat exchanger with phase change material (PCM) was investigated. Length and diameter of the tubes have been chosen such that the area of each tube to be the same. Charging and discharging processes were carried out by inner tube, outer tube and both. Results indicated, PCM melting and solidification tim...
متن کاملPartial Discharge in High Voltage Insulating Materials
High voltage transmission has been chosen in electric power system due to its capability to transfer a large amount of electric power. Several key equipments such as generator, transformer, GIS, cable and insulator play important role in determining the reliability of the power system. The high voltage equipments in general contain gas, liquid or solid insulation. Defects and a particular condi...
متن کاملApplicability of various insulating materials for radon barriers.
The effectiveness of various insulating materials for limiting radon entry into houses has been investigated under laboratory conditions. Results for the radon diffusion coefficient measurements in more than 80 insulating materials are summarized. We have discovered that great differences exist in diffusion properties, because the diffusion coefficient varies within four orders from 10(-13) m2/...
