NORM
Naturally occurring radioactive material (NORM), is found almost everywhere. It is found
in the air and in soil, and even in radioactive potassium in our own bodies. It is found in
public water supplies and foods such as Brazil nuts, cereal, and peanut butter.
Oilfield NORM
Oil and gas NORM is created in the production process when produced fluids from reservoirs
carry sulfates up to the surface of the Earth’s crust. As the fluids approach the surface,
changes in the temperature and pressure cause the barium, calcium, strontium and radium
sulfates to precipitate out of solution and form scale on the inside or, on occasion, the
outside of oil field equipment. Enhanced concentrations of NORM also occur in sludge
that accumulates in oilfield pits, tanks, lagoons and in the soil around tank batteries and
well heads.
Oil field workers may be exposed to NORM particles containing levels of alpha-emitting
radionuclides that pose health risks if inhaled or ingested.
NORM
Owner/operators are required to identify the presence of NORM in order to protect employees
and contractors working on site.
Increased industr y awareness coupled with government regulator y efforts has resulted
in better control of oil-field NORM wastes. They have reduced the radiation exposure to
workers and the public.
TEEMCO inspectors identify whether NORM is present at your facility. Both baseline and
equipment readings are taken throughout the facility and at each wellhead. You will receive
a comprehensive report detailing average NORM. This process identifies what steps if
any, need to be taken to control NORM at your sites.
The Federal Government (OSHA) and many states require the testing for NORM and
protective actions must be taken if NORM exists. Since NORM is federally regulated, even
in the absence of state regulations; all oil field facilities must be tested for NORM.
