Background: Increased exposure from background radiations and the attendant health effects have in recent times drawn attention of researchers. This study aimed to assess indoor outdoor radiation levels selected offices/industrial buildings Nnewi, Anambra State, Nigeria. Methods: Forty four villages Nnewi were surveyed using a calibrated international medicom CRM 100 monitor. Radiation readings...

Abstract Assessment of annual effective dose due to inhalation (Dinh) and ingestion (Ding) radon from 43 groundwater samples at Kantharawichai District, Maha Sarakham Province using Radon Gas Monitor ATMOS 12 DPX. The results were as follows: 1. concentrations ranged 1.04 – 21.87 Bq/L with a mean 8.26±3.77 Bq/L, 2. Dinh 2.60 54.69 μSv/y 20.70±9.40 μSv/y. Ding 0.19 3.94 1.50±0.70 μSv/y, 3. on or...

In this paper, we present a useful Monte Carlo (MC)-based methodology that can be utilized to calculate the absorbed dose and initial levels of complex DNA damage (such as double strand breaks-DSBs) in case an environmental ionizing radiation (IR) exposure incident (REI) i.e., nuclear accident. Our objective is assess doses by isolating only one component total released environment after REI wi...

The presence of heavy radioactive minerals in the studied granitoids from which Wadi sediments leads to study exposure emitted gamma rays terrestrial radionuclides, such as 238U, 232Th, and 40K. geological revealed that derived surrounding granitoids, syenogranite, alkali feldspar granite, quartz syenite. mineral analysis confirmed were enriched with minerals, uranothorite well monazite, zircon...

In this study, the specific activity of natural and artificial radioactive elements was measured for 50 sediment samples collected from throughout Miankaleh wetland in northern Iran on southeastern side Caspian Sea using a High-Purity Germanium detector. Also, radiological parameters hazard indicators due to environmental gamma radiation caused by these nuclei were calculated distribution map R...

Xiamen is one of China's most rapidly developing metropolises. The objectives of the present study were: (1) to establish the levels and spatial distribution of polycyclic aromatic hydrocarbons (PAHs) in soil across the Xiamen metropolis, (2) to evaluate the extent to which PAH concentrations were elevated in the high urbanization area (HUA) of the island and how these compared with those in th...

Radioactivity in the environment occur due to natural, terrestrial, extra-terrestrial factors or caused by human activity. Food stuffs that grown soil which containing radioactive elements may get deposited absorbed foods. Wild growing mushrooms can accumulate many types of toxicological, nutritional and elements. So, are considered as good bio-indicators determine environmental pollution radia...

Objective: The pollution free environment is required for healthy life. real-time radiation monitoring very important hazard detection in the environment. excess life-time cancer risk (ELCR) on public to assess based data area. Methods: was performed using portable digital device. This device meets all European CE standards as well American “FCC 15 standard”. placed at 1 meter above ground trip...

The aim of current research was to determine airborne asbestos fiber concentrations in the ambient air Tehran, and investigate their spatial distribution, seasonal variation, human health risk assessment. For this, sampling study carried out during August 2017 June 2018, totally, 64 samples were taken from 8 stations along different areas Tehran. fibers determined by phase contrast microscope (...

Different rock types (syenogranite, alkali feldspar granite and quartz syenite intruded by microgranite dikes veins) were investigated in the Nikeiba region Egypt. The main components of studied intrusive rocks, comprised granites syenite, are plagioclase, amphibole, biotite, K-feldspar different proportions. Ground gamma ray measurements show that syenogranite, have highest radioactivity (K, e...
