T
he
Spectral
Gamma
tool
is
a
three-channel
analysis
of
the
gross
gamma
ray
spectrum
as
it
relates
to
potassium,
uranium,
and
thorium
content.
An
internal
energy
source
of
less
than
1
micro-
curries
of
Cs137
is
used
to
excite
the
crystal
and
to
stabilize
the
electronics
prior
to
logging.
The
spectral
window
is
recorded
via
a
256
channel
spectrum
board
so
that
the
different
energy
levels
from the formation can be analyzed.
