Radioactive iodine and radioactive cesium: two important radio-hazard elements in post nuclear power plant crisis

The present nuclear leakage crisis from Japan is a topic to be discussed in present public health. In radiology, the leaked radioactive elements are considered hazard. Here, the author briefly reviews and discusses on two important radio-hazard elements in post nuclear power plant crisis, radioactive iodine and radioactive cesium. Based on previous similar nuclear crisis in Russia, it ...

Testing the Integrity of Liquid Containing Hermetically Sealed Containers by the Use of Radioactive Markers

The Use of Two Radioactive Isotopes

There are 2 radioactive isotopes of iron suitable for use as biological tracers. One of these, Fe59, has a half life of 47 days and emits gamma rays and low energy beta rays. The other, Fe55, has a half life of about 5 years and emits low energy x-rays only. This paper describes how these 2 isotopes are prepared for red blood cell tracer studies, how biological samples containing the radioactiv...

Two Asymptotic Models for Arrays of Underground Waste Containers

We study the homogenization of two models of an underground nuclear waste repository. The nuclear waste cells are periodically stored in the middle of a geological layer and are the only source terms in a parabolic evolution problem. The diffusion constants have a very large contrast between the fuel repository and the soil. It is thus a combined problem of homogenization and singular perturbat...
