Measurement of Natural Radioactivity in Sand Samples Collected from Ad-Dahna Desert in Saudi Arabia

Abstract

Natural radioactivity is a source of continuous exposure to human beings. The natural radioactivity due to the presence of 226 , equivalent to a gamma dose of 1.5 mSv·yr -1 .This study shows that the measured sand samples do not pose any significant source of radiation hazard and are safe for use in building materials.

Assessing the Radioactivity Level of Seawater and Sand Samples from the Baltic Sea Region

“…A gamma-ray spectrum of Sample 1 in the 30.00-1678.85 keV range of radiation energies is shown in Figure 4. The spectrum obtained contains characteristic lines for natural radionuclides, for example, Na-22 and Na-24 produced by cosmic radiation [18] and K-40 [19] 18 . These results con rm that the NaI detector can be used successfully to quantitatively determine radionuclides and their concentration in dry seawater sediments and salt from the Baltic Sea containing natural and anthropogenic radionuclides 20 .…”

Quantification of Silicon (SI) and Silicon Dioxide (SiO<sub>2</sub>) from the Nafud Desert-Al-Qassim Region, Kingdom of Saudi Arabia Using XRD Analysis

“…The area of study is four cities (As Sulubiayh, Al-Qawwarh, Al Fuwayliq, and Uyun Al Jawa) in the Qassim area, which is a part of the Nafud desert in Saudi Arabia. The Nafud desert is located in northern Saudi Arabia and covers an area of 57,000 km 2 [17] [18].…”

Seeking Ways for Dealing with the Impacts of Sandstorms on the Railway Network in Saudi Arabia

“…For example, the sandy deserts in Saudi Arabia are the most prominent feature and cover about 35% of the land in the country. There are three major deserts, as shown in Figure 1: An-Nafud is an upland desert of red sands because of an iron oxide coating that covers an area of 64,000 km 2 , lying in the northern part of the country at an elevation of 900 m [4]. The Rub-al-khali desert covers much of the southeast of the country and beyond the southern border, which has an estimated area of around 650,000 km 2 .…”

“…The Rub-al-khali desert covers much of the southeast of the country and beyond the southern border, which has an estimated area of around 650,000 km 2 . The Ad-Dahna desert, or reddish sandy desert, is a narrow strip of sandy terrain located in the central region of Saudi Arabia, which extends around 1300 km southward from the northwestern side of An-Nafud desert to the northwestern borders of the Rub-al-khali desert [4]. This section will concentrate on research relating to Saudi Arabian dust storms.…”
