Purpose: Radon (222Rn) and its decay products clinging to airborne particles settle in the lungs when inhaled can lead lung cancer. The main source of 222Rn is rocks soil Earth's crust causes indoor radon exposure local geological material used as a building material. Accordingly, primary objective study determine activity concentrations (CRn) exhalation rates (EA EM) from different rock types ...

Measurement of outdoor and indoor background ionizing radiation (BIR) O.B. Lulu Briggs Health Centre in the University Port Harcourt, Rivers State, Nigeria was carried out using a well-calibrated Radalert-100 (Radiation meter) Digilert-200 meters Global Positioning System (Garmin 765). 30 selected locations were considered. The results are as follows respectively, average exposure rates 0.012±0...

Introduction: Monitoring and controlling water resources and using health risk assessment approaches for water pollutants are essential for health promotion programs. This study aims to determine the water quality status and its spatiotemporal variation across the Kan River Basin, explore the interrelationship between surface and groundwater quality indices, and assess the nitrate health risk i...

background: this study was focused on the probability of carcinogen risk of low-level ingestion and dermal exposure with polycyclic aromatic hydrocarbons (pahs) from drinking water in tehran, capital of iran. methods: concentrations of 16 pahs were measured in the tap, bottled and heated tap water in four different seasons. using a questionnaire-based survey, exposure with pahs from drinking wa...

Ionizing radiations emanating from human natural environment could have serious negative effects at certain exposure level. Therefore the evaluation of radioisotopes origin becomes very important in order to achieve specific objective quantifying radiological parameters and their respective health implications. Hence estimation Activity Utlization Index (AUI) Excess Lifetime Cancer Risk (ELCR) ...

Background: Ondo city in Ondo State Nigeria includes Ondo East and West could be described as a research city due to antecedent number of research institutes. Materials and Methods: Dose due to radioactivity content of soil samples from sixteen waste dump sites in Ondo, Southwestern Nigeria was determined using gamma-ray spectrometer in order to evaluate the radiation hazard health profile and ...

The present study deals with sequential extraction of fine particulate matter (PM2.5) bound trace metals in an industrial area of Firozabad, India. During the study period, daily PM2.5 concentration ranged between 73.49 μg/m3 and 113.26 μg/m3 with poor air quality index of 196.37. In the present study, Ca recorded the highest while Co had the lowest concentration among all analysed metals. Mn, ...

This study presents the results of ambient radioactive radiation, radiation health hazard indices and excess lifetime cancer risk estimation around radiological sections in Federal Teaching Hospital Gombe, Gombe State, Nigeria using a well calibrated Rados-200 meters Global Positioning System (Garmin 765). The mean annual outdoor equivalent dose 0.078 mSv/y. was measured. Mean effective doses 0...
