CORRIGENDUM 1
Table 1 – Radionuclides and energy windows to be used for performance measurements
Instead of:
Table 1 – Radionuclides and energy windows
to be used for performance measurements
Energy window
Radionuclide
keV
99m
Tc
141, with a tolerance of ± 7,5 %
I
364, with a tolerance of ± 10 %
Ga 93, 184, 300, with a tolerance of ± 20 %
Ga 511, with a tolerance of ± 10 %
NOTE Because the characteristics of a gamma camera may change noticeably
between 122 keV (57Co) and 141 keV (99mTc), the former is not included as a suitable
radionuclide. However, it may be useful in some circumstances, e.g. for quality control.
