In summary:
•
TLD remains the standard method for single source exp dosimetry (both LE HE)
.
,
•
Methodological recommendations are included in TG43U1 (Rivard et al. 2004),
Joint AAPM-ESTRO report (Perez-Calatayud et al, 2012) and refs therein
•
At minimum calculate your correction using MC and including TLD att./volume
and p
phant
as a function of (r,θ). These are significant for LE and less for HE.

•
Overall uncertainty for LE is high mainly due to uncertainty. Dose rate constants

measured are on average ~5% higher than MC and hence the recommendation for
equally averaged, consensus values in TG43U1 (Rivard et al. 2004)

A dosimeter with reduced uncertainty would be welcome!
