“…The end was: the 40 K action focus levels in stone examples in these investigations were lower than fixation estimations of various examinations on the planet. A few examples and other stone examples were not observed to be reasonable for utilizing in the human life regions due to every single radiological incentive in these examples are higher than CLV [22].…”

This chapter deals with gamma background radiation that is exposed to two major natural sources: normal sources that are earthly gamma rays and astronomical rays. Earthbound gamma rays from radionuclide elements such as thorium, potassium, and uranium. Also, in building and enhancing materials such as medical plants, building purposes, some vegetables and fruits commonly used in markets and soil. The measurements of gamma background radiation differ according to the purpose. So, there are many instruments used such as HPGe detector, NaI (TI) detector, CR-39, a dosimeter, and SSNDT detector. This research will explain in detail the studies and the mechanism for each detector and how it works and the application (practical) studies for each one. The purpose of calculating gamma background radiation is to be in the safe side for human being according to the international union specified with a standard limitation of world average value or with a specific value ranged (standard values) according to the case study in medical, food, or building materials.

“…In recent years, radiological effects of naturally occurring radiation has received considerable attention in many countries around the world (UNSCEAR, 2000, Zivuku et al, 2018, Xinming and Wuhui, 2018, Harikrishnan et al, 2018. This has been due to their acute or chronic health effects (Reda et al, 2018, Sahin Bal, 2018Faisal et al, 2015). Beyond certain limits, radiation can cause longterm health effects such as cancer and cardiovascular diseases (William, et al, 2000;Busby, 2010, Innocent et al, 2013, Onjefu et al, 2020.…”

Radioactivity levels in salt pans from the Erongo region of Namibia have been investigated. Ten composite salt samples, collected from salt pans of the Walvis Bay lagoon were analyzed for activity concentrations of 2226 Ra, 232 Th and 40 K. This was done using a high-resolution gamma-ray spectrometer. The average activity concentrations in (Bq.kg -1 ) of 226 Ra, 232 Th and 40 K were found to be 2.17 ± 0.19, 0.20 ± 0.02 and 2.28 ± 0.39, respectively. These activity concentrations were used to calculate the annual effective dose and radiological health risk from the ingestion of salt for the different age groups. The average annual effective dose in (μSv/yr) for the age ranges (2-7 years), (7-12 years), (12-17 years) and ≥ 17 years were found to be 2.67 ± 0.22, 3.33 ± 0.28, 6.08 ± 0.53 and 1.22 ± 0.10, respectively. All these were lower than the worldwide average of 0.29 mSv/yr as reported by UNSCEAR in 2000. The total average radiological risk (unitless x 10 -8 ) for the age ranges (2-7 years), (7-12 years), (12-17 years) and ≥ 17 years were found to be 30. 15 ± 2.48, 60.30 ± 4.96, 89.8 ± 7.44 and 422.09 ± 34.75, respectively. All these were lower than the recommended limit of between 1x10 -6 to 1x10 -4 as reported by USEPA in 1991. Therefore, the results from this study indicated that the salt samples do not pose a radiological risk to members of the public.
