Radiation exposure,, environment,, absorbed dose rateAbstract
The presence of radiation in the environment could lead to health risks. Radiation exposure to humans could be through inhalation, ingestion, irradiation from external sources and more. Hence the need for reliable and unceasing measurement of background ionizing radiation. The background ionizing radiation in Ogu community has been measured and radiation hazards calculated. The radalert was used for the measurement at thirty randomly selected sampling points across. Results show that background ionizing radiation, absorbed dose rate, annual effective dose equivalent as well as excess life cancer risk ranges from (0.006 – 0.026) with average of 0.012 , (52.20 – 226.20) with average of 104.40 , (0.50 – 2.19) with average of 1.01 , (0.080 – 0.347) with average of 0.160 and (0.280 – 1.215) with average of respectively. Plots from the results show that nearly all measured points have values above world averages except for equivalent dose. This is an indication of probability of developing radiological consequences by residents of Ogu after exposure for a long time.
