Half Life Verification
Intended Use
The Half Life Verification APP is intended to check a radioactive isotope to determine the actual
Half Life of the isotope sample.
Indications For Use
In a Nuclear Pharmacy it is common practice to test certain isotopes for contamination from
other isotopes before use. This test is typically performed for PET isotopes such as F-18. The
Half Life is calculated from either two or three timed activity readings in the dose calibrator.
The system then calculates the actual Half Life of the sample and shows the variance
percentage to the system listed isotope Half Life. It is the user’s responsibility to determine if
this variance is acceptable.
Half Life Verification App
(See Figures 5.9 – 5.17.)
The Half Life Verification APP allows the user to select the isotope, set test parameters; select
either 2 or 3 readings and set the elapsed time between the readings. The time can be set
between 1 minute and 60 minutes. You can also enter the lot number. When the test is
complete, print your results. The results show the preset Half Life for the isotope selected and
the calculated Half Life from the two or three activity readings.
NOTE: The dose calibrator does not store the Half Life calculation. You can print the results.
NOTE: It is up to the user to decide if this variance is acceptable or if there are too many
contaminants in the isotope to use it.
