Dr. Lancuam. The basic concepts of this problem have not changed
since the previous hearings. All that can be added which is neware
the results of the collection of additional data which allowus to define
some of the parameters better and to make calculations that I think are
considerably more accurate.
The second thing that has changed the picture since the previous
hearing is the resumption of weaponstests both by the U.S.S.R. and
the United States. J will not elaborate particularly on what these
improvements in data are in the interest of trying to get us back on
schedule, but rather I will refresh your memory to say that the
radiation effects of worldwide fallout will be due to a number of components. These I am sure are familiar to most of you. Thefirst, of
course, is strontium 90—strontium 89—those substances which because
of their chemical similarity to calcium deposit in bone produce skeletal
irradiation exposure. The next component of worldwide fallout is
