A. But the attention of the layman, not surprisingly, has been captured by the atom bomb, although there is at least a chance that it may never be used again.
B. Of all the changes introduced by man into the household of nature, [controlled] large-scale nuclear fission is undoubtedly the most dangerous and most profound.
C. The danger to humanity created by the so-called peaceful uses of atomic energy may, however, be much greater.
D. The resultant ionizing radiation has become the most serious agent of pollution of the environment and the greatest threat to man’s survival on earth.

Explanatory Answer
B is the best opening sentence. B states that large-scale nuclear fission is dangerous. D explains how so. So, BD is a sequence about the danger posed by large-scale nuclear fission. Statement A adds to BD, explaining that the attention of the layman, however, directed at the atom bomb instead. C talks of a danger that may be much greater: the danger to humanity by so-called "peaceful uses" of atomic energy. So, BDAC is the correct order.
