DESCRIPTION:
Gallium
Citrate
Ga67
Injection is supplied in isotonic solution as a
sterile,
non-pyrogenic
diagnostic
radiopharmaceutical
for
intravenous
administration. Each milliliter of the isotonic
solution contains Gallium Citrate Ga67 1.5-2
mCi, at the time of calibration, Sodium Citrate
1.5-2 mg and Sodium Chloride 0.9% sol. The
pH
is
adjusted
to
between
5-8
with
hydrochloric
acid
and/or
sodium
hydroxide
solution. Gallium Ga67, with a half-life of 78.3
hours,
is
cyclotron
produced
by
the
proton
irradiation of enriched zinc oxide, is essentially
carrier-free
and
contains
negligible
concentrations of other radioactive isotopes.
The radionuclidic composition at calibration
time is not less than 99.89% Gallium Ga67,
less than 0.01% Gallium Ga66 and less than
0.1% due to other radio contaminants, each
expressed as a percentage of total activity. The
radionuclidic composition at calibration time is
not less than 99.89% Gallium Ga67, essentially
zero (0.0002%) Gallium Ga66 and essentially
zero
of
other
radio
contaminants
each
expressed as a percentage of total activity.

PHYSICAL CHARACTERISTICS
Gallium Ga67 decays to stable Zinc Zn67 by
electron capture with a physical half-life of
78.3 hours.
