description

The compact and popular reading device features a linear, adjustable heating system and cooling photomultiplier tube, which can be combined with electronic components to measure the thermal luminescence output. Running WinREMS software on a Du Li computer provides a user interface, reader control, and application software.

• Easy to operate, service, and maintain, with measurement quality assurance of up to50 of themThe unmanned automatic operation thermoelectric PMT cooler of the dosimeter provides multiple, adjustable, linear time temperature curves with high gain stability and automatic background subtraction functions; The heating curve includes preheating, acquisition, and annealing cycles using a linear non-contact hot gas heating method, with a temperature range of up to 600 ° C (1112 ° F) and dynamic acquisition of 7 orders of magnitude every 30 seconds. Normal TTP can withstand falling from a height of 20 millimeters onto cement ground. The ambient lighting can withstand up to 1000 lux of light (covered by the reader), including computer-processed deconvolution luminescence curve software, neutral filter, and calibration software

  Dose measurement performance when using LiF: Mg, Ti (TLD-100):

• Organizational equivalence: approximate organizational equivalence
• Batch uniformity: ± Batch uniformity standard deviation of 15%, can be reduced when special requirements are met. Residual TL signal:<0.2% when not annealed. Sensitivity change<10% for each dosimeter after more than 500 measurements. Threshold:<10 μ Gy (1 mrad). One unirradiated dosimeter is repeated 10 times, based on 2.26 standard deviations
