“…Because they are probabilistic and presume that any exposure can have an effect, these effects are referred to as stochastic effects [6]. The presence of rock materials and other building materials coupled with laboratory chemicals may influence the background radiation of the environment [11]. The current study's goal is to establish baseline data for future radiation effect assessments and, if necessary, radiation protection measures by measuring dose rates in order to assess health hazards, if any, and compare equivalent doses.…”

A Study of indoor and outdoor radiation dose rate level measurements for male and female hostels at the Federal University of Kashere Hostels, Gombe State, Nigeria, has been carried out with the radiation alert smart 4 to ascertain the radiation level. The measured radiation dose rates were used to calculate the excess lifetime cancer risk and assess radiological health risks. The mean annual outdoor and indoor equivalent doses were 0.025 mSv/y. and 0.370 mSv/y. were recorded, with less than 1 mSv/y. maximum recommended limit for the general public. The mean annual outdoor and indoor effective doses were 0.017 mSv/y. and 0.086 mSv/y. respectively with a total of 0.103 mSv/yr. respectively. were computed. Mean outdoor and indoor ELCR values of 0.061X10-3and 0.302X10-3 respectively, with a mean total of 0.363X10-3 were also computed.

The study focuses on measuring the values of 238 U, 232 Th and 40 K natural radionuclides in soil samples in Badra oil field area (Iraq). Also, the radiological risk data were calculated for all samples in this study. The technique used in this study was gamma-ray spectrometry with NaI(Tl) detector. The averages of specific activity are: 24.7 Bq/kg for 238 U, 13.6 Bq/kg for 232 Th, and 538.9 Bq/kg for 40 K. Besides, the estimations of radiological effects like the radium equivalent (Ra eq ), the absorbed dose rate (D r ), external hazard index (H ex ), internal hazard index (H in ), representative gamma hazard index (I γ ) and the total annual effective dose equivalent (AEDE) are 85.5 Bq/kg, 42.1 nGy/h, 0.23, 0.30, 0.66 and 0.26 mSv/y respectively. When comparing the results in the study area with the world mean values specified by the UNSCEAR, OCDE and ICRP, the study terminates that the limits of health risk are safe and may not menace the workers at these locations due to these radionuclide limits. The values were subjected to GIS environment under the WGS1984 coordinate system for the sake of results' coordination, and processed in Inverse Distance Weighted interpolation as the best processing.

Radon activity concentration was measured in 101 springs and well water samples collected from Muzaffarabad city and its outskirts. Sixty springs and 41 well water samples were analyzed, using RAD7, an electronic radon detector manufactured by Durridge Company Inc., for the estimation of radon borne activities and their relevant effects. Results obtained show that for spring water, the water borne radon activity varied from 0.246 ± 0.348 to 34.36 ± 5.54 Bq L−1 with an average value of 10.16 ± 2.42 Bq L−1. For well water, the water borne radon activity varied from 0.86 ± 0.10 to 16.12 ± 0.22 Bq L−1 with an average value of 4.21 ± 0.13 Bq L−1. Concentration of radon borne activities were subsequently used for determination of inhalation and ingestion doses. The inhalation and ingestion doses for spring water samples varied from 0.0062 ± 0.0087 to 0.865 ± 0.14 mSv y−1 and 0.052± 0.073 to 7.22 ± 1.16 mSv y−1, respectively. The inhalation and ingestion doses for well water varied from 0.022 ± 0.0025 to 0.41 ± 0.0054 mSv y−1 and 0.18± 0.021 to 3.38 ± 0.045 mSv y−1, respectively. 33.33% of spring and 7.32% of well water samples were found with values above the recommendation levels of the United States Environmental Protection Agency (∼11.1 Bq L−1). As a single measurement cannot serve as a best estimate of the unsampled areas in the region, Kriging interpolation method, a geo-statistical method, was used to get an estimate of spatial distribution of water borne radon in the area of study. Kriging mapping shows that higher radon concentrations are found in areas with lithology consisting of sandstones, siltstones, shales and claystones.
