facter in heference 16.) An attonpt has been made to corvect for this
he plots shown in Fisure 5,2,
This figure, taken
rom Reference 10, is a graphical representation of the directional
response to a lOsag Radium source of a 118 instrument in the horizontal
and in two vertical planes, It was felt to be sufficiently accurate
to make the approximation shown in the raph by setting a straisnat line
Lindi’ to the response vector in one re,ion and, further, to ascume that
the response is cylindrically syvmetric about the XX't axis, Maxinun
sensitivity,
indicated by a vectur length of unity, is thea in the JA
direction on the XX! axis.

flux intensity):
