Medical knowledge on ionizing radiations
I have read with great concern the article written by Borém et al. (1) – " The knowledge about diagnostic imaging methods among primary care and medical emergency physicians " –, published by Radiologia Brasileira in December/2013. The presented results show in a hard-hitting way that physicians are educated even without an appropriate idea about what is ionizing radiation, radiological imaging...
متن کاملEffects of Ionizing Radiations on Immune Processes
establishment of new neural connections rather than the modification of existing sets. Blinded octopuses can acquire certain kinds of discriminations based upon tactile or chemical stimulation. The results of a textual discrimination experiment with grooved cylinders suggest that the "discrimination of the topographical features of objects touched may be based simply upon the proportion of sens...
متن کاملRadiation Effects and Damage 1. Ionizing Radiations
The detrimental consequences of radiation are referred to as radiation damage. To understand the effects of radiation, one must first be familiar with the radiations and their interaction mechanisms. Further, the fundamental characteristics of the material(s) being irradiated must also be understood. A brief summary of the characteristics of radiation is first presented below. This is followed ...
متن کاملThe assessment of function, histopathological changes, and oxidative stress in liver tissue due to ionizing and non-ionizing radiations
Background: Compared to past decades, humans are exposed to rapidly increasing levels of radiofrequency electromagnetic radiations (RF-EMF). Despite numerous studies, the biological effects of human exposure to different levels of RF-EMF are not fully understood, yet. This study aimed to evaluate the bioeffects of exposure to "900/1800 MHz" and “2.4 GHz" RF-EMFs, and x-rays as well as their pot...
متن کاملStudies of the inactivation of viruses by ionizing radiations (i.e. X-rays and the radiations
Three bacteriophages (S-13, C-36 and S taph-K ) were irrad ia ted by y-rays, X -rays and a-rays. The survival curves were exponential, and the effect of a given dose was independent of the exposure tim e. F or any given phage the inactivation doses of the three radiations increased in the order y-rays, X -rays, a-rays, while for any given rad iation the inactivation doses of the three phages di...
