in this paper are present the results of measurements of magnetic induction at some locationsin city bor (the east serbia) dating from the household electric devices and transformer stations suited near the residental areas. stress is on the extremely low frequent electromagnetic radiation from transformer stations and other high voltage instalations in urban areas. risk of the extremely low fr...

abstract nowadays, solar energy as one of the most important sources of clean and free of damaging environmental effects energy are used in many cases including generation of electricity, heat and desalination of salt water. the purpose of this research is identification of high radiation areas as most suitable regions for these applications.to do this, cloudiness data of 120 synoptic stations ...

introduction iron ore is one of the most important natural raw materials that is widely used for manufacturing iron and steel. this type of ore contains various amounts of radionuclides; thus, exposing workers handling their extraction, transportation, and processing to radiation. materials and methods in this study, 12 ore samples (each mass weighing about 2 kg) were collected from the iron or...

Ionizing radiations are one of the predominant exogenous factors that have deleterious consequences to human life The biological effects of the radiation cause damages to DNAs, lipids and proteins. Exposure to high amounts of ionizing radiation causes damages to the hematopoietic, gastrointestinal or central nervous systems, depending on radiation dose. Hence, there is an urgent need to prevent...

background: the activity concentrations of some radionuclides in soil samples collected from 20 locations in 8 major towns in oyo state, southwestern nigeria have been determined by gamma-ray spectrometry technique. materials and methods: the activity concentrations were determined using high-purity germanium (hpge) detector (canberra industries inc.). the outdoor absorbed dose rates in air at ...

Telomere length and stability is a biomarker of aging, stress, and cancer. Shortening of telomeres and high level of DNA damages are known to be associated with aging. Telomere shortening normally occurs during cell division in most cells and when telomeres reach a critically short length, DNA damage signaling and cellular senescence can be triggered. The induction of an adaptive response by sp...

human’s disregard to nature and consequently his living environment’s distance from natural endowments and potentials have caused many problems. human’s living spaces are less desirable for him, and have destroyed his comfort in many cases, as man-made things. in this regard, public open spaces in residential areas can be mentioned because they are usually considered among the most vulnerable s...

Background: Humans beings are continuously exposed to ionizing radiation from natural sources. The main contributors to natural radiation are high-energy cosmic radiation and radioactive nuclides that originates in the earth’s crust. Exposure to high levels of radiation can cause serious health effects. In this study an attempt has been made to monitor the levels of environmental back...
