In this study, we will investigate the radiation activity of 20 soil samples from five schools in Mosul Province were measured the gamma spectrum by using NaI (TI) Discovery which has dimensions 3*3 crystal. The activity concentrations of naturally occurring of 40K ranged from (310.414±3.40 to 1359.220±1.37) Bqkg−1, 238U reached from (1.035±0.300 to 62.636±0.108) Bq kg−1 and 232Th ranged from (0.583±0.060 to 24.139±0.47) Bq kg−1while the average activity concentration observed 40K was 936.340 ± 3.88 Bqkg−1, 238U was 18.861±0.391 Bqkg−1and 232Th was 5.376 ± 0.312Bqkg−1. The radiological hazard parameters (representative level index, radium equivalent activity, outdoor and indoor dose rates, outdoor and indoor annual effective dose equivalents, and radiation hazard index) were calculated from the radioactivity in the soil. Results of the present work concerning values of radium equivalent activity, outdoor annual effective dose rates, the gamma index, and internal and external hazard indices, all were found to be lower than their corresponding allowed limits given by the world average. The data produced in the present work can be used as baseline radiological data for future investigations.

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.

“…Also literature showed that studies on radionuclide concentrations in mines have been extensively in national studies (Hussein, 2018;Azeez et al, 2018;Ahmed and Samad, 2014;Dashty and Ali, 2013;Makki et al, 2014;Hussain and Hussain, 2011;Hussain and Abbas, 2010;Ali, 2011;Kamal et al, 2015). Mining activities have not been subjected to radiological regulatory control and so there is generally little or no awareness and knowledge of the radiological hazards.…”

In this work, the activity concentrations of natural radionuclides 226Ra, 232Th and 40K in soil samples from Erbil governorate, Iraqi Kurdistan were investigated by a gamma-spectroscopy system based on high-purity germanium (HPGe) detector. This is to assess the dose of radionuclides exposure to the population, knowing the health risks and to have a baseline for future changes in the environmental radioactivity. It was found that the activity concentrations of 226Ra, 232Th and 40K were ranged from (14.6 ± 1.6 to 38.2 ± 2.8 Bq.kg-1), (4.5 ± 1.4 to 52.4 ± 5.8 Bq.kg-1) and ( 302.8 ± 12.6 to 388.6 ± 12.8 Bq.kg-1), respectively. The measured activity concentrations for these radionuclides were compared with the reported data of other countries and with the worldwide average activity of soil. Radium equivalent activities, absorbed dose rate, excess lifetime cancer risk and the values of hazard indices were calculated for the measured samples to assess the radiation hazard of the natural radioactivity in all samples to the people. It was concluded that the radium equivalent activities of the studied samples are below the internationally accepted values. These results show that annual effective dose absorbed via occupant from activity construction of soil samples used in the under place is below 1.0 mSv.y-1. It is concluded that the assessment radioactivity of soil are within acceptable levels and does not pose any health hazard to the population.
