Influence of N + ion bombardment on LiF (TLD-100) sensitivity
Abstract
The thermoluminescence (TL) sensitivity of the LiF (TLD-100) dosimeter to γ-rays under the influence of N + ion bombardment has been investigated. Several groups of LiF dosimeters were consequently bombarded by a flux of ions ranging from 3.1 × 10 13 to 25 × 10 13ions/cm 2·s -1, at different exposure times before and after an annealing range of temperature: 50-150°C. The results show a relative increase in the dosimeter sensitivity with a maximum of ∼ 36% when pre-treated for 10 min with a 4 keV ion beam having a particle flux of ∼21 × 10 13ions/cm 2·s -1, at an annealing temperature 150°C. This increase was decaying to its standard value after the fourth γ-exposure-readout cycles.
