Long-term radiation exposure affects human health. Ionizing radiation has long been known to raise the risk of cancer. In addition to high doses of radiation, low-dose ionizing radiation might increase the risk of cardiovascular disease, lens opacity, and some other non-cancerous diseases. Low- and high-dose exposures to ionizing radiation elicit different signaling events at the molecular leve...

background: although ionizing radiation is very important in diagnostic and treatment of many diseases, the hazards of this radiation are considerable and irrefutable. one of the main stages in radiation protection is knowledge about radiation dose in radiological investigation. the aim of this study was to determine the physicians' knowledge in radiological examinations. materials and methods:...

Introduction: Retinoblastoma (RB) is a malignant retinal tumor, which affects infants and children. This cancer happens through a mutation in the retinoblastoma tumor suppressor genes (RB1). Inactivation of RB1 has been observed in more than 97% of all retinoblastoma patients with mutations. In recent years, RB treatment has developed significantly. RBchr('39')s treatment methods can be one or ...

the space environment consists mainly of high-energy charged particles, such as protons, electrons and heavy ions. they are originating from several sources including galactic cosmic radiation, solar flares and van allen belts. high energy electromagnetic radiation and neutrons have also been measured on spacecraft. although shielding can reduce the effect of space radiation it cannot be elimin...

mobile phones, mobile phone base stations, cordless phones and power lines are among the main sources of our daily exposures to radiofrequency electromagnetic fields (rf-emf). today, a large proportion of children aged eight and under has used smart phones and tablets for media activities such as playing online games, watching videos or using different applications. over the past several years,...

introduction : the  rapid development  of wireless telecommunication technologies  over the past decades, has led to significant changes in the exposure of the general public to electromagnetic fi elds. nowadays, people are continuously exposed to different sources of electromagnetic fi elds such as mobile phones, mobile base stations, cordless phones, wi-fi routers, and power lines. therefore,...

Ionizing and non-ionizing electromagnetic field (EMF) radiation, either stand-alone or in combination with other agents, exert health effects on biological systems. The present chapter examines the scope of non-ionizing EMF radiation combined effects; i.e., identifies effects on biological systems from combined exposure to non-ionizing electromagnetic fields/radiation and at least one other age...

ionizing radiation causes dna damage and chromosome abbreviations on normal cells. the radioprotective effect of celecoxib (clx) was investigated against genotoxicity induced by ionizing radiation in cultured human blood lymphocytes. peripheral blood samples were collected from human volunteers and were incubated at different concentrations at 1, 5, 10 and 50 μm of clx for two hours. at each do...
