Dose Related Relationship of Depleted Uranium Associated with Certain Blood Electric Properties

Abstract

In many radiation applications, there are clear dose effect relationships. On the other hand, there are many confusions about the radiation dose relationship that comes from depleted uranium on blood. Time study (0-16 hours) of three concentrations of uranyl acetate (1, 2 and 4 mM), which can reflect radiation dose multiplications, is used as depleted uranium on stored human blood. The exposed blood dielectric properties were measured using the three frequencies method at 25, 500 and 1000 KHz; the three doses at the different time intervals were compared. We find that some electric properties are not affected by increasing the dose during the whole time interval. No significant changes in neither the cell interior resistance nor in relative permittivity at 25, 500 and 1000 KHz at all the time interval, thus no dose relationship can be detected from them. The significant changes in plasma resistance, cell membrane capacitance and dielectric loss (at 25, 500 and 1000 KHz) are at only 9 hours of exposure and are dose related while there is no significant change at any other time interval. So we conclude that some electric properties if measured at certain time of exposure can give dose related relationship of depleted uranium on blood.
