Two flowers on each female plant were pollinated with pollen from the selected male parent of that population. Mature pollen was exposed to one of the following doses of y-rays, at a rate of rads per minute—25, 100, 400, x6oo and 6400 rads, and used immediately afterwards for ...
The effect of the male-female body-size difference on absorbed dose-rate distributions in humans from natural gamma rays 来自 NCBI 喜欢 0 阅读量: 26 作者: K O'Brien 摘要: Previous calculations of the natural gamma dose to human organs and tissues were based on the MIRD phantom, a 70 kg...
Humans are exposed to ionising radiation from many sources, including naturally occurring radionuclides (cos- mic and terrestrial, e.g. radon gas), certain occupations (e.g., cardiologists and power plant workers), various diagnostic tests and medical therapies (e.g., x-rays or radiotherapy) ...
Cells were exposed to either a single dose of 1-Gy 137Cs-gamma-rays or to 1 microM arsenite (As(III)) or to both agents in combination. Two-dimensional (2D) electrophoresis and matrix-assisted laser desorption/ionisation-time of flight (MALDI-TOF) were employed for the screening and ...

due to the use of geologic materials in dwellings. This radiation has received less attention than man-made sources because it contributes less to the total doses that affect humans, on the average. However, there are geographical areas and rocks used as building materials that contain high conc...
We studied the effects of dexamethasone, ascorbic acid, and metronidazole on the irradiated spinal cord of Wistar rats. Thirty adult Wistar rats were randomly assigned into 3 groups. Five rats served as the control group. Another group of 5 rats were irradiated in the neural axis with 2.5 Gy...
