A sleeve shield package to perform linearity tests on dose
calibrators.
Used in the Moly Breakthrough Test to shield the radiation
of the Tc-99m in an eluent so that the activity of the Mo-99
can be measured.
Used to determine the percentage of parent Mo-99 remain-
ing in the eluent containing the daughter Tc-99m radionu-
clide.
The parent radionuclide which decays into the daughter Tc-
99m, used to generate radiopharmaceuticals.
National Institute of Standards & Technology, whose activi-
ties include maintaining radioactive material standards.
Nuclear Regulatory Commission, which is the agency of the
Federal Government which regulates radioactive materials.
The Atomlab unit automatically selects which range of
Display units (µCi or mCi, or MBq or GBq) to be used for
the Activity Display to show activity values with the most sig-
nificant number of digits.
The variation of the ion current collected by an ionization
cham ber because of individual decay processes associated
with different radioisotopes. Calibration Values are required to
adjust the output of the electrometer for each radioisotope to
compensate for this variation in response, thereby ensuring
accuracy over the entire range of commonly used radioiso-
topes.
A method of performing linearity tests on a dose calibrator
by encircling a single source with leaded sleeves of varying
thickness, thereby reducing the activity the dose calibrator
measures by a known amount. Comparison of the expected
and actual activity values constitutes the test of linearity.
