Abstract

Radon is a colorless, odorless indoor and outdoor air pollutant that is produced by uranium disintegrations (decay). It represents at least half of the typical population's ionizing radiation exposure due to man-made and natural origin. Attention was paid to radon due to its harmful radiological effect on public health. Population have for all time been exposed to radon and its progeny since they are naturally occurred and enter homes through a variety of pathways such as buildings (such as ceiling, walls & floor), Water, Soils and rocks. Radon detection is rarely important because it is not known to exist unless there is a wellbeing distress. The quantity of radon present within water, rock-soils and buildings varies on a number of variables. According to the retrieved studies, indoor radon levels are generally higher during the cold and wet seasons than they are during the summer. This systematic review focuses on the radiological implications arise from high exposure to radon and the elevated probability of happening of wellbeing harms in exposed residents of Nigeria. Previous research on radon concentrations in Nigeria received the most attention. Only a few studies provided evidence supporting the link between outdoor and indoor radon concentrations and radiological implications analyses, such as the evaluation of cancer risk from radon inhalation and ingestion yet within areas of extremely high concentrations. On the other hand, a few studies also revealed a tendency for adverse effects on public health to occur still within circumstances where indoor radon concentrations be lesser. According to data derived from published articles by Nigerian researchers, radon exposure caused some little concern over the association between radon concentration and determinations of radiological impact. Therefore, it is crucial to evaluate the radiological effects of radon, comprehend the dangers of exposure, and determine how inhabitants in Nigeria who are exposed to it may suffer health effects. The best course of action to prevent the harmful consequences of radon gas in an indoor or outdoor environment is to stop its production. Preethi and Jeyanthi offered some methods for radon mitigation in buildings. Depressurization, freshening, and sealing fall under these categories, with related percentage effectiveness ranges of 50-80%, 80-95%, and 50-70%.
