Outlines on Protection of Workers from Ionizing Radiations.

The health of workers exposed to ionizing radiations.

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...

Oxygen Protection of Bacteriophage T1 against Ionizing Radiations

Bacteriophage T1 was suspended in distilled water and in phosphate buffer, saturated with oxygen, nitrogen, hydrogen, and carbon monoxide, and irradiated with gamma rays and x-rays. Under the same conditions phage was exposed to hydrogen peroxide. Oxygen acted as a protective agent against both irradiation and hydrogen peroxide inactivation. As a protective agent against irradiation, oxygen was...

Effects 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...

Enhanced Frequency of Chromosomal Aberrations in Workers Occupationally Exposed to Ionizing Radiations

The yield of chromosomal aberrations was analyzed in peripheral blood cultures to estimate the level of radiation exposure in workers from a radioprotection department. The subjects were exposed at low level dose rate (external exposure) to alfa, beta and gamma rays for time periods ranging between 7 and 34 years. We found a higher frequency of dicentrics and acentrics than in the control group...
