Data from multi year and multi radiation detector measurements of different radiation sources with environmental data.

The data described consists of radiation measurement outputs from several different detectors located in Abu Dhabi, UAE, for the duration of 30 November 2014 through 13 December 2016. This data could be useful for anyone studying radiation count rate or spectroscopic changes over a multi year period from various radiation sources and measurement systems. The outputs of the measurement systems include 1) counts per 20 min from a Geiger-Muller detector measuring 90Sr, 2) counts per 20 min from a Geiger-Muller detector measuring 204Tl, 3) radiation spectra per 30 min from a NaI detector measuring 60Co, 4) radiation spectra per 30 min from a NaI detector measuring 54Mn, 5) radiation spectra per 30 min from a liquid scintillation detector measuring 226Ra, 6) counts per 30 min from a liquid scintillation detector measuring 14C, and room pressure, temperature, and humidity data every 10 min. A detailed description of the setup of each of these measurement systems can be found in "Experimental Setup and Commissioning Baseline Study in Search of Time-Variations in Beta-Decay Half-Lives" [1].

Whole body effective dose equivalent dataset for MAX and FAX shielded with Common Aerospace Materials in deep space.

Materials have a primary purpose in the design of space vehicles, such as fuels, walls, racks, windows, etc. Additionally, each will also affect space radiation protection. Using the On-Line Tool for the Assessment of Radiation in Space (OLTARIS), version 3.5, analysis package, this article includes the whole body effective dose equivalent (ED) data from human phantoms being shielded by 59 aerospace materials for deep space travel. To represent the average anatomy of an astronaut, the Female Adult voXel (FAX), 2005 version, and the Male Adult voXel (MAX), 2005 version, human phantoms are used. A simple spherical geometry, which is composed of a spherical shell with the human phantom placed in the center, is also used. Eighteen shielding thicknesses ranging from 0.01 to 1000 g per centimetres squared are evaluated and the ray distribution used in this study is the 1002 geodesic. All aerospace materials are categorized into four groups: metals, polymers, composites, and fuels, hydrides, and liquid gases. These materials include common fuels and propellants used in space travel, engineered materials developed to significantly increase the absorption of secondary radiation, and materials in the early stages of development for the purpose of meeting both shielding and structural needs of future spacecraft missions. The data in this article is used for the paper, "Evaluating the Effectiveness of Common Aerospace Materials at Lowering the Whole Body Effective Dose Equivalent in Deep Space," [13].

LOSS OF TLD SIGNAL DUE TO HIGH TEMPERATURE ENVIRONMENTAL CONDITIONS.

While it is known that temperatures above 100°C have an effect on the reported dose of a TLD, it is less widely known what the susceptibility is to temperatures below 100°C, temperatures humans could reasonably expect to be exposed to. With the expanding nuclear industry in climates with more extreme temperatures, (e.g. United Arab Emirates and Saudi Arabia) the effect on a TLD if left on a dashboard of a car need to be evaluated. This research experimentally determined the extent of this thermal susceptibility by testing a range of high temperatures, 40°C - 90°C. The experimental results found that there is a statistically significant reduction in TLD-100H (natLiF:Mg,Cu,P) light output for TLDs there were exposed to temperatures as low as 40°C for 8 hour durations and 50°C for 2 hour durations. There is statistical difference in TLD-100H light output for elevated temperature durations of 8 hours compared to 24 hours.

Evaluation of background radiation dose contributions in the United Arab Emirates.

The natural background radiation consists of three main components; cosmic, terrestrial, and skyshine. Although there are currently methods available to measure the total dose rate from background radiation, no established methods exist that allow for the measurement of each component the background radiation. This analysis consists of a unique methodology in which the dose rate contribution from each component of the natural background radiation is measured and calculated. This project evaluates the natural background dose rate in the Abu Dhabi City region from all three of these components using the developed methodology. Evaluating and understanding the different components of background radiation provides a baseline allowing for the detection, and possibly attribution, of elevated radiation levels. Measurements using a high-pressure ion chamber with different shielding configurations and two offshore measurements provided dose rate information that were attributed to the different components of the background radiation. Additional spectral information was obtained using an HPGe detector to verify and quantify the presence of terrestrial radionuclides. By evaluating the dose rates of the different shielding configurations the comic, terrestrial, and skyshine contribution in the Abu Dhabi City region were determined to be 33.0 ±â€¯1.7, 15.7 ±â€¯2.5, and 2.4 ±â€¯2.1 nSv/h, respectively.
