The shadow minimization problem for
t-intersecting systems of finite sets is considered. Let
$
{\user1{A}}
$
{\user1{A}}
be a family of
k-subsets of
$
{\user1{A}}
$
{\user1{A}}
is the set of all (
k-
$
\partial _{{\ell }} {\user1{A}}
$
\partial _{{\ell }} {\user1{A}}
contained in the members of
$
{\user1{A}}
$
{\user1{A}}
. Let
$
{\user1{A}}
$
{\user1{A}}
be a
t-intersecting family (any two members have at least
t elements in common) with
$
{\left| {\user1{A}} \right|} = m
$
{\left| {\user1{A}} \right|} = m
. Given
k,t,m the problem is to minimize
$
{\left| {\partial _{{\ell }} {\user1{A}}} \right|}
$
{\left| {\partial _{{\ell }} {\user1{A}}} \right|}
(over all choices of
$
{\user1{A}}
$
{\user1{A}}
). In this paper we solve this problem when
m is big enough.
