Mining has been identified as one of the potential sources of exposure to naturally occurring radioactive materials (NORM).However,mining companies are not being regulated for NORM in Sierra Leone until when recently the Nuclear and Radiation Safety Bill was revised and passed into law upon the recommendation made by the IAEA.Whilst the developed countries have identified NORM as potential problems and measures are being taken to address the issues,very little is being done in the developing countries.However,most of the NORM industries such as mining and mineral processing are located in developing countries like Sierra Leone.Currently,there are over one hundred (100) registered mining companies operating small,medium and large scale mining in Sierra Leone.Cluf Gold is one of the largest gold mining companies in Sierra Leone and has been in operation for a number of years with no data on radioactivity levels.The mine currently undertakes only surface mining and the process produces large volumes of tailings and waste that may contain NORM.Gombu Smert is local mining company engaged in mining coltan/tantalum oxide which contain naturally radioactive materials such Uranium,Thorium and Radium.The Sierra Rutile mines undertakes both wet and dry mining and also produces large volume of tailings containing NORMS.The workers and the public are exposed to the NORMS with limited supervision.The Offshore Oil and Gas exploration and production produces large volume of waste containing significant amount of NORM.Some of the NORM are soluble in water and have the tendency to leach into water bodies and farm lands.NORM leaching water can be swallowed by fish and other aquatic animals making them radioactively contaminated.When these contaminated aquatic animals such as fish,shrimps etc are sold in the market,then the public is affected.This is infact a global concern as contaminated fish can be sold all over the world if measures are taken to combat the risk.The exposure of the public to NORM from processing of gold ore at the Goldmine,Rutile,Coltan and tantalum oxide,iron ore etc were analyse for U/Th series and K-40 in soil,rock and particulate (dust) samples from the mining environment.The mean activity concentrations measured for 238U,232Th and 40K in the soil/rock samples were 15.2 Bq/kg,26.9 Bq/kg and 157.1 Bq/kg respectively.The annual dose for the public was estimated to be 0.74 mSv.The results indicate an insignificant exposure of the public to technologically enhanced NORMS from the activities of the mines.Currently,a number of investors have shown interest to mine uranium in Sierra Leone but Uranium mining is yet to approved by the Government.Sierra Leone is a country blessed with over twelve (12) natural minerals,some are presently being mined and the others are yet to be mined.
