“…The NaI(Tl) gamma-bar spectrometer has high efficiency, and in a similar manner, it might be used for the customary radioactivity. The outcomes acquired in this examination were analyzed inside the cutoff points of values gotten in different urban areas of Turkey, those in different nations [19].…”

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.

Twenty four samples of various granites and marble used common as flooring materials were collected from many factories and market in Baghdad Province, Iraq. Natural radioactivity of 226 Ra, 232 Th and 40 K in the samples was measured by using high purity germanium detectors with an efficiency of 40%. The Specific activity concentration in granite samples ranged from 9.20 to 79.64 Bq/kg, 10.50 to 229.40 Bq/kg and 185.30 to 1391.20 Bq/kg for 226 Ra, 232 Th and 40 K, respectively. The estimated of radiological parameters: radium equivalent activity (R eq) , activity concentration Index (I) and hazard indices (internal (H in ) and External (H ex )) that associated with the radiation hazard in the samples. The results of activity specific concentrations and radiological parameters of 226 Ra, 232 Th and 40 K were compared with the reported data of the worldwide limit of building materials.

“…Chernobyl and Fukushima released radioactivity producing worldwide radionuclide contamination in addition to the nuclear weapons testing in the atmosphere upto 1963 and from some subsequent venting of underground tests (Han and Park 2018;Jia et al 2005). Greater than half of total radioactive dose is associated with inhaled radioactivity associated with airborne particulate matter of different sizes (Sahin et al 2017;Tabar et al 2017).…”

In this study, the activities of 40 K, 210 Pb, 232 Th, 234 U, 235 U, and 238 U in size-segregated particulate matter (PM) were measured in the Singrauli Coalfield, India. Different isotopic compositions were found relative to natural uranium ratios. The radioactivity concentration ratios in different PM sizes [PM 2.5 , PM 10 , and suspended particulate matter (SPM)] suggested that anthropogenic sources affected the uranium isotopic compositions in the area. A different isotopic composition from the natural uranium composition was found. The correlation coefficients between the measured isotopes (40 K, 210 Pb, 232 Th, 234 U, 235 U, and 238 U) and meteorological factors were calculated. PM emissions were affected by the meteorological conditions, which in turn, influenced the U and Th concentrations in PM. The 232 Th/ 238 U activity ratio in particulate matter was between 0.20 and 1.54 with an average value of 0.9 ± 0.5, 0.2 to 1.1 (0.8 ± 0.7), and 0.2 to 1.2 with an average value of 0.8 ± 0.8 in PM 2.5 , PM 10 , and SPM, respectively. These range were quite different from the average crustal ratio of 3.5, indicating that the 238 U concentrations were elevated in this region relative to Th. However, compared with Th, the dose contribution of U to the public was negligible. The average effective dose in public owing to inhalation of natural radioactive 40 K, 210 Pb, 232 Th, and 234 U, 235 U, and 238 U in the atmosphere was between 0.03 and 327 nSv year −1. These doses associated with the inhalation of particulate matter were lower than world airborne reference value as reported by UNSCEAR (2000a).
