Radiation
A
projectile
electron
interacts
with
and
knocks
out
an
inner
shell
electron
producing
a
very
unstable
atom
.
In
order
to
stabilize
itself
,
and
outer
-
shell
electron
fills
the
vacancy
in
the
inner
-
shell
and
in
this
process
,
an
x
-
ray
is
emitted
.

Radiation
A

interacts
with
a

nucleus
which
causes
an

to
be
emitted

The
electron
slows
down
and
changes
its
direction
.
This
is

X
-
ray
)
An
interaction
between
low
-
energy
x
-
rays
and
matter
causes
scatter
radiation
.
The
X
-
ray
changes
direction
but
does
not
lose
energy
.
There
is
no
energy
transfer
,
so
there
is
no
ionization
.
This
can
occur
throughout
the
diagnostic
range
and
therefore
,
contribute
to

Effect
(
most
form
of
scatter
)
An
interaction
between
moderate
energy
x
-
rays
and
the
outer
-
shell
electrons
of
matter
causes
scatter
radiation
.
The
outer

shell
electron
is
knocked
out
which
causes
a
loss
of
energy
and
ionizes
the
atom
.
This
is
the
primary
form
of

This

If
