substances continued until the beginning of June 1986. It is still not clear if the dumping of these materials actually achieved their goal. Recent data has shown only a small part of the materials actually got into the well. Due to the accident, the people of Chernobyl were exposed to radioactivity 100 times greater than the Hiroshima bomb. The people of the world and Northern Europe were greeted with clouds of radioactive material being blown northward through the sky. Seventy percent of the radiation is estimated to have fallen on Belarus and 10 years later babies are sill being born with no arms, no eyes, or only stumps for limbs. No one can predict the exact number of human victims. It is estimated that over 15 million people have been victimized by the disaster in some way.

It has also estimated that ultimately the accident will claim more victims than World War II. It will cost over 60 Billion dollars to make these people healthy. Thirty-one lives were lost immediately, and more than 600,000 people were involved with the cleanup. Many are now dead or sick. Hundreds of thousands had to abandon entire cities and settlements within the thirty-kilometer zone of highest contamination. Possibly as many as three million still live in contaminated areas. Ten thousand of these are still living in the city of Chernobyl today. Huge sums of many have been spent, and will continue to be spent to relocate settlements and decontaminate the once rich farmlands. Chernobyl has developed as an icon for the terror of uncontrolled nuclear power and abilities, and for

Soviet deception and inability to provide safe conditions for workers and basic services such as transportation and health care, especially in times of greatest need. The catastrophe also halted a highly potential nuclear program. The impact of the Chernobyl Accident on a Nuclear Energy Policy is tremendous. Some countries stopped national nuclear energy programs. Construction of new plants in the Soviet republics were frozen. Public opinion was directed against nuclear power plants. Some plants were even shut down, but have now been reactivated. The accident has also initiated an international activity in the area of nuclear safety and nuclear emergency planning. Many countries started a development of decision support systems for nuclear accident cases. The way in which Soviet

leaders have dealt with the situation is very unsettling. In the aftermath of the catastrophe several designs to encase the damaged reactor were reviewed. The option that was selected included the construction of a massive structure in concrete and steel that used what remained of the reactor walls as support. Its construction is considered one of the most complicated building works in the world. In charge of building the tomb was Construction Department No. 605. They ran into many problems while constructing the massive concrete and steel shell. Concrete blocks for the tomb were pieced together far from the reactor itself, and the roads entering the facilities were not accommodated for such loads, which made it difficult for the drivers. Once the blocks were delivered, the

workers needed to put them in place. Each weighed several dozen tons so eventually crane operators had to perform this task. This outer protective wall, 28 stories high, is placed around the perimeter and other walls connected to the Unit 3 reactor. A steel roof then completed the structure. The destroyed reactor was entombed in a 300,000-ton concrete structure known as the “shelter” or “envelope.” In conditions of high radioactivity the mammoth task was completed in seven months, in November 1986. The site around the plant had then been announced safe for about the next thirty years. However today the sarcophagus is cracked and crumbling. Some of these cracks are as large as a garage door. Multiple sensors were placed to monitor levels of gamma radiation, neutron flux,

temperature, heat flux, as well as the concentrations of hydrogen, carbon monoxide and water vapor in the air. Other sensors monl On the whole, there are some different points and aspects from the authors to explain the effects of immigration on labor market. They are the demand and supply, investment, expenditure form government, skilled immigrants, mobility and the empirical findings. Although there are both advantages and disadvantages from immigration, most authors believed that there is no causal link between immigration and unemployment. However, it is possible that they emphasized the benefits and gave insufficient attention to the costs of immigration on the labor market. In my view, government should consider more aspects from the effect of immigration on labor market
