Coal combustion is a source of multiple pollutionssulphur and nitrogen oxides particles mercury cadmium arsenicum etc. It is difficult to remove contaminants from coal before burnning. Coal washing may create just an additional problem. Some modern technologies to control polutions still can not bring them to the environmentally save level.

TENORM Oil and Gas Production Wastes Radiation

Like contaminated scale sludge contains more Ra-226 than Ra-228. The average concentration of radium in sludges is estimated to be 2.775 Bqg 75 pCig. This may vary considerably from site to site. Although the concentration of radiation is lower in sludges than in scales sludges are more soluble and therefore more readily released to the .
