TABLE IL.
Tower Shots
2, The relationship between the functions of Table I and il
and the probability of acceptable weather conditions to permit
execution of tests has not yet been completed.
However, a review
of past shots does give a fairly clear picture of these relationships.
3. Table III presents pertinent information of past shots
and general extent of fallout.
4, It will be noted that there exists considerable
variation in extent of the fallout distances for shots having
similar megacuries of fallout.
This is due to several factors,
the principal one being the weather conditions under which the
particular shot was detonated,
In the past,
the weather con-~
ditions under which shots have been detonated have varied
considerably.
Table IV indicates the wide range of extent of
fallout that can occur for shots having the same amount of
potential megacuries of fallout.

Table IV also lllustrates the
It lllustrates that by taking
advantage of the best suitable weather conditions it is possible
to reduce greatly the extent of the fallout pattern.
However,
to
accomplish this on shots in the higher megacurie fallout brackets
