TLD: intrinsic energy dependence
•
is in the order of 0.90
±
0.05 to 0.935
±
0.03 for I-125 and Pd-103
•
This correction appears to be protocol and TLD make specific.
•
A correction might be needed for HE sources as well
(Joint AAPM-ESTRO report suggests
) but for Ir-192 Carlsson et al. (Med.
Phys. 39(2), 1133. 2012) suggests
but with increased uncertainties
(3.5%, k=1).
