For the purposes of this problem assume that there was an instantaneous release of 10⁷curies of radioactive gases (and fine particles, which are assumed to remain in the atmosphere and not settle out). Then estimate the maximum ground level concentration of radioactive gases (curies/m³) when the radioactive cloud from the accident got to Sweden. Make the following assumptions: (1) Ignore decay of the radioactive gases (i.e., assume their half-lives were infinite). (2) Assume the distance between Chernobyl and Sweden is 1000 km. (3) Assume that the wind speed was 3 m/s and the stability class C. (4) Assume that the mixing height was 2000 m. (5) Assume that mlXmg in the x direction(up and down the direction of the wind) has the same intensity as miXing in the y(crosswind)direction.

Why is this？ Although the total growth rate of the world population will decrease(下降), in some countries there will be a big rise in the population. More people will be born in Third World countries than in the richer Northern countries. So the population will grow faster in poor countries; and the problems in these countries will be very serious. This is because the family is more likely to survive(幸存) if there are a lot of children to work for the members who become old or who cannot find work. A survey of the UN also shows that the growth rate is low where there is a higher level of income, better education, more health care and better living conditions. In this aspect, government plays an important role. So, the conclusion of the UN report is: "Look after the people and the population will look after itself." What can we learn about the growth rate of population？ A．The total growth rate of world population will increase. B．The growth rate of population in richer countries will increase. C．The growth rate of population in poor countries will increase. D．The total growth rate in American countries will increase.
