Abstract Humans have always been exposed to different types of natural and cosmic radiation. At present we experience 83 % radiation, for example from granite marbles, building materials such as concrete, brick, granite, or drywall. However, although these are potential sources radon, they rarely the cause a high level pollution in building.Ashlar is material volcanic origin comprising heteroge...

The radioactive material in urine after parenteral radioactive hydroxocobalamin is composed of radioactive cyanocobalamin, radioactive hydroxocobalamin, and a radioactive anionic complex. Studies in vitro suggest that these materials have a similar microbiological activity. Comparison of the amounts of radioactive and microbiologically active material in urine after parenteral radioactive hydro...

The present publication is the third of four reviews reports that have been published over last 20 years to address responses arboreal plants at different hierarchical levels their organization anthropogenic factors. Here, impact types industrial pollution on radial accretion stock and rootage considered. Most studies evidence leads unequivocal decreases in sensitivity climatic cues, redistribu...

Abstract The rapid proliferation and intensive use of electronic devices have led to an increase in pollution, such as noise, electromagnetic interference (EMI), radiofrequency (RFI), which cause malfunctions devices. emergence flexible polymer composites has a remarkable potential for shielding depending on their unique characteristics, electrical, thermal, mechanical, magnetic properties, are...
