The dose-response of LiF:Mg,Ti (TLD-100) exposed to 15 and 35 kVp (
and
keV effective energy respectively) x-rays and
-rays has been measured in the dose interval from (1.2-5.4)
Gy for x-rays, and from 0.14 to 850 Gy for
-rays. In both cases the total TL signal and glow curve peaks 3 to 9 show supralinearity. The supralinearity function f(D) is similar for both x-ray beams, except for peak 8, where a 30% difference is observed. The maxima of f(D) for the total TL signal and peaks 5 to 8 are 2.1, 1.7, 6.4, 3.3 and 7.5 respectively for 8.1 keV x-rays and 3.7, 3.1, 13.6, 9.9 and 11.0 for
-rays. The measured relative efficiencies for x-rays with respect to
, for the total TL signal and peaks 5 and 7, were 1.04, 0.97 and 3.2 respectively.
