SwRI Information

	Autoradiograph of leaf from Phacilia robusta shows preferential uptake of radium from soil affected by uranium deposit.

Technologically enhanced naturally occurring radioactive material (TENORM) is generated by a variety of processes such as:

• Mineral extractions and refining

• Hydrocarbon production

• Water treatment

Southwest Research Institute (SwRI) has an active program developing cost-effective and environmentally responsible approaches for managing TENORM waste.

The SwRI TENORM program currently focuses on land disposal of TENORM waste. Investigations examine release of radon gas from land disposal units, such as municipal solid waste landfills that have or may receive radium-bearing TENORM from drinking water treatment, petroleum production, or other activities. Research includes analysis of the mobility of naturally occurring radionuclides in soil and their uptake by vegetation.
 

Landfill gas venting produces an atmospheric radon plume from buried radium-bearing waste.

TENORM Expertise

The TENORM program provides expertise and scientific services in:

• Radiochemistry

• Environmental process modeling

• Probabilistic risk assessment

• Environmental regulatory compliance

	SwRI's radiochemistry laboratory includes facilities for bench-scale testing environmental samples and remedial technologies.

At SwRI, the TENORM program is supported by:

• Advanced laboratory facilities for radiochemical analyses and bench-scale testing of radionuclide transport and stabilization processes

• Public domain and proprietary models for multimedia modeling and probabilistic risk assessment

• Facilities for large-scale pilot testing of environmental technologies on SwRI's 1,200-acre site

Radon flux through the surface of a landfill containing TENORM.  The simulation is based on five landfill gas extraction wells.
