title: LiSr4(BO3)3:Ce3+ phosphor as a new material for ESR dosimetry.
abstract: LiSr4(BO3)3:0.01Ce(3+) phosphor was investigated to assess its potential as a material for measurements of radiotherapeutic doses with electron spin resonance (ESR). The ESR spectrum of the phosphor irradiated with (60)Co features five ESR signals. An isochronal annealing experiment has shown that the strongest of these signals is associated with the same trap center as the 473 K peak on the TL glow curve of this material. The dose-response is linear in the studied range from 0.89 to 90.30 Gy. Fading of the signal was also investigated.
