MANAGEMENT OF NORM IN THE PETROLEUM INDUSTRY Akpojevwa Tega Naomi, october 2016 | Page 7

ABSTRACT Naturally Occurring Radioactive Materials (NORM) waste in oil and gas extraction and processing, tends to accumulate at concentration above normal in by-product waste streams. In the past, the presence of elevated NORM concentrations has been largely unregulated. These radioactive NORM waste are hazardous to the environment and to human health above a particular dose rate of exposure at about 1mSv (1millisierviet) per annum and should therefore be managed by regulatory framework put in place at both national and international level. In this regard, many countries including Nigeria has responded in the same manner. It is necessary that there is a need for adequate surveillance in oil and gas producing sector of the Nigeria economy, for NORM waste detection and proper management. vii
