“…232 Th, 137 Cs, 40 K and 238 U Radioactive elements are important radioactive elements in soil [1]. There are different methods for measuring the specific activity of these elements [2]. One of these methods is the use of CsI (Tl) scintillation detectors, which have been reported in several reports on their use for this purpose [3,4].…”

The radiation hazards in each region depend on its surface distribution and activity of 232Th, 137Cs, 40K, and 238U radioactive elements. Due to the presence of personnel, professors, and students in the Graduate University of Advanced Technology (KGUT) environment, it is important to investigate the dose received due to 232Th, 137Cs, 40K, and 238U elements in the soil of this area. For this purpose, first, 44 soil samples were collected from different areas of the university, and the specific activity of 232Th, 137Cs, 40K, and 238U elements was obtained with the CsI (Tl) scintillation detector. Then, using radiation hazard equations, the distribution of radiation hazard parameters at the university zone has been calculated. The research results show that the average specific activity of 232Th, 137Cs, 40K, and 238U elements at the university zone is equal to 13.51, 4.53, 47.64, and 13.01 Bq/kg. The activities of 232Th, 40K, and 238U elements are below the permissible limit and 137Cs is higher than the permissible limit. Also, the average of Raeq, DY, Dout, Din, Dtot, Hex, Hin, Iγ, and ELCR radiation hazard quantities are 81.26 (Bq/kg), 72.31 (mGy/y), 0.088 (mGy/y), 0.088 (mGy/y), 0.17 (mGy/y), 0.11, 0.15, 0.18 and 0.62 respectively. According to the results the DY and Dout radiation hazards are more than the permissible limit and the rest of the radiation hazard parameters are less than the permissible limit. Results have shown that the Annual Effective Dose outside (soil) and inside (soil and granite) of the KGUT office building was (22 ± 0.22) μSv/y, (0.13 ± 0.0013) mSv/y. Finally, the distribution of natural radioactive elements and radiation hazards in different parts of the university shows that except for DY and Dout, all radiation hazard parameters in the administrative buildings and dormitories of the university are less than the permissible limit. Therefore, the annual presence of staff, students, and professors in the university are allowed.

“…As a result of this, several authors have used this technique to screen the radioactivity level in different matrices [8][9][10][11][12][13]. Due to the possible risks of background radiations on the human health and, in particular, their presence in building materials used to construct dwellings, it is so necessary to screen these materials and determine the order of magnitude of radioactivity level as well as the hazards, which is the main objective of the present study.…”

The objective of the present study is the screening of the gross alpha and gross beta activity of some building materials commercialized in Saudi Arabia. The measurements were carried out using a gas flow proportional counter. The study has shown that the gross alpha activity ranged between 0.21 and 8.27 Bq/kg with an average activity of about 1.96 Bq/kg, whereas the gross beta activity ranged between 6.47 and 276.47 Bq/kg with an average activity of about 65.27 Bq/kg. The obtained values of gross alpha and beta activities are in the worldwide range and no significant activity was observed that accentuate the attention, which show that no radiation risks come from these building materials and, therefore, from their origin areas.
