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 Еще
