This study aims to low level background range measurements of commercial OSLDs. This includes generating the differential equation to express all source contributions for low dose in OSLDs by considering thermal decay, radioactive decay, and background.In the first part of the study, the dosimeters used to measure background dose were measured in two different ways; one was measuring&nbsp;each dosimeter 30 times in sequence without removal or replacement of the dosimeter, the second was then done by sequentially measuring each dosimeter 30 times with full removal and replacement for each measurement.As a result of these measurements, initial dose, bleaching constant, and background dose was evaluated for different kinds of measurements, and analysis of variance was applied to see whether or not there is any difference in results. This allowed an assessment of the error contributions from the placement of the dosimeter independent of all other error components.To analyze results, the same analysis method was applied to both the first and second measurement via ANOVA. Additionally, all measurements are considered as a measurement data set and analyzed. Consequently, it was observed that there is a statistically significant difference in these different kinds of measurement approaches relative to the total propagated&nbsp;uncertainty in any given&nbsp;dose estimate.

2021 28th International Conference on Nuclear Engineering (ICONE28)

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
