We developed and characterized Monolithic pixel detectors in deep-submicron Fully Depleted (FD) Silicon On Insulator (SOI) technology. This paper presents the first studies of total dose effects from ionizing radiation performed on single transistor test structures. This work shows how the substrate bias condition during irradiation heavily affects the resulting radiation damage.

background: from the time immemorial man has been exposed to ionizing radiation from the environment in which he lives. radiation protection concepts and philosophy have been evolving over the past several decades. materials and methods: the radioprotective of effect of aloe vera leaf extract (1000 mg /kg b.wt. orally for 15 consecutive days) has been studied against 6 gy of gamma radiation in ...

background: astronauts will be exposed to both chronic space radiation and acute high doses of energetic radiation of solar particle events in long-term deep space missions. the application of radioprotectors in space missions has basic limitations such as their very short time window as well as their acute toxicity and considerable side effects. the aim of the present study was to investigate ...

The mouse histone H2AX has unique COOH-terminal serine residues that are phosphorylated in response to double-strand DNA breaks introduced by ionizing radiation. This suggests that H2AX acts to maintain genomic stability. We constructed a tetracycline (tet)-directed turn-off vector and integrated it into F9 mouse teratocarcinoma cells by homologous recombination. In homozygously recombined cell...

The ionizing radiation of livestock wastewater for the removal of nitrogen and phosphorus was studied in the presence of a natural zeolite. The feasibility of a combined process of zeolite ion exchange and electron beam irradiation of livestock wastewater was also investigated. The removal efficiencies of NH4-N, T-N and T-P were significantly enhanced by electron beam irradiation after zeolite ...

Aminothiols such as WR-2721 and its active free thiol WR-1065 have previously been shown to reduce mutations resulting from ionizing radiation in exponentially growing cells. In this study, non-dividing human G0 T-lymphocytes were exposed to the aminothiol radioprotective agent, WR-1065, 30 min before or 3 h after external beam gamma-irradiation and subsequently assessed for survival and mutati...

We investigated the sucrose radical-production cross-section induced by heavy-ion irradiation. L-alanine was also used in order to compare radical yield and cross-section. The stable free radicals after irradiation were analyzed by electron paramagnetic resonance (EPR). The radical yield obtained by the irradiated samples had a logarithmic correlation with the LET (linear energy transfer). Quan...

In this review we discuss alarming epidemiological and experimental data on possible carcinogenic effects of long term exposure to low intensity microwave (MW) radiation. Recently, a number of reports revealed that under certain conditions the irradiation by low intensity MW can substantially induce cancer progression in humans and in animal models. The carcinogenic effect of MW irradiation is ...

Ionizing radiation produce deleterious effects in the living organisms and the rapid technological advancement has increased human exposure to ionizing radiation enormously. There is a need to protect humans against such effects of ionizing radiation. In this study, the effect of Haberlea rhodopensis and vitamin C on the frequency of chromosome aberrations in rabbits peripheral blood lymphocyte...

In spite of the technologies developed during the last decade, the level of food loss is still high and is reported in many countries. According to the United Nations, more than 30 per cent of the mortality rate world-wide is caused by alimentary diseases. The desire of most countries to make food safer for consumption requires better food preservation and production techniques. In this regard,...
