“…The samples were analyzed at Reactor Engineering Section of the Centre for Energy Research and Training (CERT), Ahmadu Bello University (ABU), Zaria, Nigeria using a Miniature Neutron Source Reactor (MNSR) by means of Instrumental Neutron Activation Analysis (INAA) technique. INAA can analyse NORMs, race, minor and major elements in different sample types (Arabi et al, 2016). The reactor uses high-enriched uranium as fuel, and light water as a moderator and coolant.…”

“…The annual effective dose for the public is 1mSvy -1 as set by Arabi et al, 2016. This is the effective dose that can be received by the public with fewer risks from the effect of ionizing radiation, though cumulative value could be higher when added to the dose received from cosmic radiation.…”

“…The external hazard index is an evaluation of the hazard of the natural gamma radiation (Arabi et al, 2016;Mujahid, S. A. et al, 2008), while the internal exposure to radon and its daughter products are quanti ed by the internal hazard index (H in ), (Mujahid et al, 2008;Xinwei, 2004). A plot of these parameters (Fig.…”

“…Marine-deposited phosphate typically has a higher level of radioactivity than igneous phosphate deposits because of the presence of uranium in seawater (Abou El-Anwar et al, 2017). Long-live radioactive elements such as uranium ( 238 U), thorium ( 232 Th) and potassium ( 40 K) and any of their decay products, such as radium and radon are examples of naturally occurring radioactive materials (NORMs) (Arabi et al, 2016).…”

Activity concentration of Naturally Occurring radioactive Materials in samples from superphosphate industry was determined using Neutron Activation Analysis and radiological parameters calculated. Mean Annual Effective-Dose Equivalent(mSv/y), External and Internal Hazard, Annual Gonad Dose Equivalent(mSv/y), Radium Equivalent (Bq/kg), Absorbed Gamma Ray Dose(nGy/h), Potential Toxic Elements, Activity Utilization, and Gamma Representation Index are 87.0, 0.4, 0.5, 517.7, 137.3, 70.9, 20101.3, 9388.9, and 1.1, respectively. Most of the sample had activity concentrations of naturally occurring radioactive materials exceeding world average, indicating that activities of the industry impact on the environment. These results are good baseline data for future follow-up on activities of company.

“…Radon emanates from rocks and easily migrates and enters the groundwater bodies that fracture (Arabi et al, 2016;Khan et al, 2022). Although radon can occur in almost all rock and soil types, the concentration differs with different sites and geological materials (Singh et al, 1999).…”

The present research was carried out to investigate the behavior of radon (222Rn) concentrations over the carbonate and evaporite sequences and to assess the related health hazards. A total of 50 points from three different stratigraphic units, namely, the Bahadurkhel Salt, Jatta Gypsum, and the Kohat Formation of the Eocene age, were analyzed for radon concentrations in the district of Karak, Khyber Pakhtunkhwa, Pakistan. Measurements for radon levels were made by using RAD7 of Durridge, United States. The highest average 222Rn concentration (16.5 Bq/L) was found in the limestone unit of the Kohat Formation of the Eocene age. However, the lowest radon levels were observed in the salt-bearing strata of the Bahadurkhel Salt of the Eocene age. The study revealed that the average radon concentration in all the lithologies varied in the order of RnLimestone > RnSalt > RnGypsum. The findings of the current research suggest that the study area is safe from radon-related health hazards.
