“…They concluded that the differences may be due to variations in levels of industrial activities in the area. Similar increase in environmental radioactivity in other cities in Nigeria has also been reported (Ajayi, 2001;Kuforiji et al, 2003;Arogunjo et al, 2004;Isinkaye and Ajayi 2006;Ajayi et al, 2006;Ademola, 2008;Farai et al, 2008;Farai and Ademola, 2005;Alatise et al, 2008;Inyang et al, 2009). This study involves the determination of ionizing radiation levels around bottling and pharmaceutical facilities in Ilorin metropolis with a view to assessing whether the radiation profile is within tolerable limit.…”

“…Industrial activities account for a significant percentage of contribution to total environmental pollution and general degradation of the natural environment that we experience today (Oke 2004;Inyang et al, 2009;EEA, 2011). Our environment contains naturally occurring radioactive materials, which spontaneously disintegrate to form stable nuclei and in the process release radiation to the environment (IAEA, 2004).…”

Measurements of ionizing radiation and corresponding dose rate around bottling and pharmaceutical facilities in Ilorin, Nigeria, have been carried out using three duly calibrated Radalert Nuclear Radiation Meters and Global Positioning System. The survey meters were held at 1 m above the ground surface while obtaining readings at 31 locations within the study area. Measured radiation levels range from 1.14±0.09 to 2.48±0.13 mSv/yr with a mean of 1.60±0.26 mSv/ yr. The result shows that the exposure rates for all the stations are higher than the radiation dose limit of 1 mSv/yr for individual members of the public, while three stations are above the global average of 2.4 mSv/yr. It is recommended that areas with readings above global average be monitored closely to protect the public from adverse health effects.

“…For effective monitoring, the radiation meter was placed at the gonad level of 1m above ground level with the window of the meter directed toward each site and 10 readings taken in different directions in each site and the mean recorded. Measurements of exposure levels in this investigation were taken in the afternoon between 1000 hours and 1700 hours for effective response of the meter to environmental radiation exposures within Calabar [8]. The measured mean background ionising radiation (σ) is converted to annual equivalent dose rate (HTc) using equation 1 […”

Radionuclides are found in different media including, soils, air, water, plants, vegetables, and in fruits etc. These radionuclides and their isotopes contaminate the environmentand could cause deleterious effect on human beings when ingested or inhaled. The cocoa plantation is a new plantation developed two years ago in the State for resource management and enhanced cocoa production. In situ measurement of the background ionising radiation was conducted with Radex (1212) radiation survey meterwhich measured background ionising radiation level in micro Seviert per hour. The measured values were converted to annual equivalent dose rate and annual effective dose. The mean background ionizing radiation (BIR) measured was obtained as 0.083µSv/hr and a mean annual BIR of 0.727mSv/yr. The obtained mean annual BIR obtained is lower than the worldwide BIRof 2.4 mSv/yr. The annual equivalent dose rate of radiation obtained in the plantation was ranged between 0.1261 to 0.2067mSv/yr with a mean value of 0.1454 mSv/yr. The mean annual effective dose was 0.1015 mSv/yr and lower than the recommended 1 mSv/yr as a safety limit for the public. Therefore regulatory controls are not necessary for now as this is a new plantation.

“…Wastes made up an environmental and public health nuisance in major cities all over the world. Thus, governments regard waste management as vital social service whose budgetary provision is made in line with population projections [17] . Hazards caused by such dumpsite are not only in term of odor and presence of disease causing microorganism, but can arise from the radiation emanating from such dumpsite [18] .…”

This research reports an assessment of ionizing radiation in some chosen Dumpsites in Lafia Local government area of Nasarawa State. Ionizing radiation measurement was conducted at four Dump sites. The survey was done using a radiation survey meter (Radex one Outdoor 55130719 NA). Radiation exposure rate in micro sievert per hour (μSvhr-1) was measured. Readings were taken by placing the detector at gonad level about 1 meter above the ground. Result showed that the average annual effective dose rate in the selected dumpsites were 0.22 mSv/yr for Lafia modern market, 0.17 mSv/yr for dumpsite opposite governor Isa house, 0.15 mSv/yr for Timber shade Lafia and 0.20 mSv/yrfor Science School Lafia respectively with a mean value of 0.19 mSv/yr for all location, while the mean calculated excess life cancer risk (ELCR) is 0.65 x 10-3.Dumpsites yearly absorbed dose rate and their corresponding ELCR values did not exceed the 1.0 mSv/y Basic Safety Standard set for the masses by International Council on Radiation Protection (ICRP, 1999) and mean world average ECLR value of 1.16 x 10-3. Based on these results there are no radiation consequence to the scavengers, dumpsite workers and residents living around the dumpsites.
