“…This conclusion drawn from the numerical simulation corresponds very well to the abrupt increase of radioactivity of the surface air at Honshu Island reported by Higuchi et al (1988). The quantitative model verification for Japan is depicted in Fig.…”

A 3-dimensional (3-D) hemispheric tracer model is employed for the long-term simulation of the dispersion of the nuclear debris from the Chernobyl accident. The most important features of the model are a fully three-dimensional advection4iffusion equation and a simple diagnostic parameterization of the boundary-layer mixing, dry deposition and wet scavenging. The tracer model is driven by a series of meteorological fields derived from the hemispheric objective analysis scheme of the Canadian Meteorological Center (CMC). The accident scenario employed in the simulation was derived from the data presented at the post-accident meeting of the International Atomic Energy Agency (IAEA) in Vienna in August 1986. Verification of the model indicates good accuracy and substantial improvement compared to the preliminary experiments with a very simple 2-dimensional (2-D) hemispheric tracer model.

“…The highest concentration of 137 Cs (7.5 Bq m À3 ) was observed on 20e21 March, as was the highest concentration of 134 Cs (6.1 Bq m À3 ). These levels are about 100 times those observed in Japan at Chiba and Tsukuba after the Chernobyl accident (Aoyama et al, 1986;Higuchi et al, 1988), and about 2000 times those observed at Tokai-mura in 1964 at the height of atmospheric nuclear weapons testing (Amano, 1996).…”

“…Twenty Chernobyl radionuclides were detected in two plumes in early and late May 1986, with the highest level in northwestern Japan and a maximum concentration on May 5. Chernobyl-derived stratospheric fallout continued until the end of 1988 (Higuchi et al, 1988;Imanaka and Koide, 1986). There is still a high probability of small but dangerously radioactive areas in the Caucasus; Trans-Caucasia; lower, central, and middle Asia (including Turkey, Iran, Iraq, and Afghanistan); China; and the Persian Gulf area, continuing until the present time.…”

Radioactive contamination from the Chernobyl meltdown spread over 40% of Europe (including Austria, Finland, Sweden, Norway, Switzerland, Romania, Great Britain, Germany, Italy, France, Greece, Iceland, Slovenia) and wide territories in Asia (including Turkey, Georgia, Armenia, Emirates, China), northern Africa, and North America. Nearly 400 million people resided in territories that were contaminated with radioactivity at a level higher than 4 kBq/m(2) (0.11 Ci/km(2)) from April to July 1986. Nearly 5 million people (including, more than 1 million children) still live with dangerous levels of radioactive contamination in Belarus, Ukraine, and European Russia. Claims that the Chernobyl radioactive fallout adds "only 2%" to the global radioactive background overshadows the fact that many affected territories had previously dangerously high levels of radiation. Even if the current level is low, there was high irradiation in the first days and weeks after the Chernobyl catastrophe. There is no reasonable explanation for the fact that the International Atomic Energy Agency and the World Health Organization (Chernobyl Forum, 2005) have completely neglected the consequences of radioactive contamination in other countries, which received more than 50% of the Chernobyl radionuclides, and addressed concerns only in Belarus, Ukraine, and European Russia.
