Forests and fresh water bodies have been among the most affected ecosystems. In most cases, these workers were not equipped with individual dosimeters to measure the amount of radiation received, so experts could only estimate their doses.

Contamination from the Chernobyl disaster was not evenly spread across the surrounding countryside but scattered irregularly depending on weather conditions.

Psychological consequences Psychological effects are of considerable importance Havenaar et al. Some of the people who dealt with the emergency lost their lives. Initially they were faced with the problem that, although many countries were exposed to radioactive fallout, it was regarded as an internal matter by the country in which it occurred. The deposition of radionuclides was governed primarily by precipitation occuring during the passage of the radioactive cloud, leading to a complex and variable exposure pattern throughout the affected region, and to a lesser extent, the rest of Europe. A key element of that strategy for recovery was to be a body called the International Chernobyl Research Board ICRB , with a broad assignment including making recommendations for research. These reported data were corroborated by the International Chernobyl Project. Further information: Fission products Immediately after the disaster, the main health concern involved radioactive iodine, with a half-life of eight days. Among the patients surviving radiation sickness, complete normalization of health took several years. Over the period , 19 survivors died for various reasons; however, some of these deaths were due to causes not associated with radiation exposure. The immediate and short-term effects resulting from heavy fallout exposure include radiation sickness and cataracts. It predicted about 30, to 60, excess cancer deaths, 7 to 15 Times greater than the figure of 4, in the IAEA press release; warned that predictions of excess cancer deaths strongly depend on the risk factor used; and predicted excess cases of thyroid cancer range between 18, and 66, in Belarus alone depending on the risk projection model. The U. Chronic stress and posttraumatic stress disorders.

Cancer risks attributable to low doses of ionizing radiation: assessing what we really know. Even where dosimeters were used, dosimetric procedures varied - some workers are thought to have been given more accurate estimated doses than others.

Further evidence for elevated human minisatellite mutation rate in Belarus eight years after the Chernobyl accident. This predicted death toll includes the 47 workers who died of acute radiation syndrome as a direct result of radiation from the disaster, nine children who died from thyroid cancer and an estimated people who could die from cancer as a result of exposure to radiation.

The number of people whose lives were affected by the disaster is enormous. Abnormalities included partially albinistic plumage, deformed toes, tumors, deformed tail feathers, deformed beaks, and deformed air sacks. Evaluating the exposures received by the people who had been evacuated or who were still residing in the areas most affected by the accident required much time and effort.

Possible increases in thyroid cancer have been reported in the Czech Republic and the UK, but more research is needed to evaluate thyroid cancer incidences in Western Europe". It started collecting a variety of biological samples from patients on 1 October and since July has been a source for ethically available tissue samples - specifically extracted nucleic acids and tissue sections - for 21 research projects in Japan, Europe and the USA.

These workers received an estimated average dose of millisieverts These reported data were corroborated by the International Chernobyl Project. The result was a serious lack of coordination and a fair measure of chaos on both humanitarian and research fronts. Livestock were removed during the human evacuations. It showed that earlier assessments had significantly underestimated the doses. Initially they were faced with the problem that, although many countries were exposed to radioactive fallout, it was regarded as an internal matter by the country in which it occurred. Among these, about individuals were treated for acute radiation sickness; 28 of these died within a relatively short time WHO a. The reactor was destroyed in the accident and considerable amounts of radioactive material were released to the environment. Because of the intense heat of the fire, and with no containment building to stop it, part of the ejected fuel was vaporized or particularized and lofted high into the atmosphere, where it spread.

It is also too soon to make an accurate assessment of longer-term effects from those already observed. Today, there is concern about contamination of the soil with strontium and caesiumwhich have half-lives of about 30 years.
