Examination of Radioactive Contamination in Foods

Nutritional hazards caused by radioactive contamination of foods.

Isotopes that may contaminate crops Fallout may be made up of a hundred or more active isotopes but only a few of them are likely to be harmful as crop contaminants. Iodine. As 1311, it will be a major hazard for a few weeks after fallout arrives. Chamberlain & Chadwick (1953) showed that iodine gas is deposited on grass by diffusion. Chamberlain, Loutit, Martin & Russell (1955) note that, in f...

Radioactive contamination of scintillators

Low counting experiments (search for double β decay and dark matter particles, measurements of neutrino fluxes from different sources, search for hypothetical nuclear and subnuclear processes, low background α, β, γ spectrometry) require extremely low background of a detector. Scintillators are widely used to search for rare events both as conventional scintillation detectors and as cryogenic s...

A Critical Review of Arsenic Contamination in Sri Lankan Foods

Numerous studies have shown growing information indicating the contribution of food to the dietary exposure of arsenic (As) through consumption of different food items in many different regions over the world. However, few review papers with regard to As in Sri Lankan foods are available in databases. Thus, a critical review and assessment of a number of local studies on total As concentrations...

Examination of Radioactive Contamination in the Soil-Plant System and Their Transfer to Selected Animal Tissues

This paper investigates gamma emitter radioactivity in a system consisting of soil and plants. Some selected samples of tissues of animals fed with the plants from these sites were also measured. In soil and plant samples artificial (Cs, Cs) and natural (thorium and uranium series) isotopes were detected. Despite the relatively high content of the natural isotopes in plants and their seeds, the...
