If there be such errors, or flaws, however, the Committee does not apologize for them, but rather asks the reader to accept them as being inherent to the technical nature of the area and the difficulty in collecting information concerning it.

For instance, ‘the personification of "Bravo" as a “sleeping giant" whose radioactive cloud behaved as if influenced by “trickster ghosts" may be considered repugnant or perhaps improper by some scientists. Be this as it may, no one can deny=--not even the most prominent scientists--that the radioactive legacy of such an event has continued to "live" until this day both in a purely physical and biological sense and in a psycholocical sense. In writing this report, the Committee has attempted to popularize and simplify the subject of radiation and its effects. The very subject of radiation is a very complex and large one, a fact which is indicated by the remark of one scientist in talking about radioactive An
