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.
•
What you don’t know (phantom composition, density, etc) goes in your uncertainty
budget!
•
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!
