Ionizing radiation measurements and assay of corresponding dose rate around bottling and pharmaceutical facilities in Ilorin, Nigeria
Abstract
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.
